This book was released on 2011-05-13 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landslides represent one of the most destructive natural catastrophes. They can reach extremely long distances and velocities, and are capable of wiping out human communities and settlements. Yet landslides have a creative facet as they contribute to the modification of the landscape. They are the consequence of the gravity pull jointly with the tectonic disturbance of our living planet. Landslides are most often studied within a geotechnical and geomorphological perspective. Engineering calculations are traditionally applied to the stability of terrains. In this book, landslides are viewed as a physical phenomenon. A physical understanding of landslides is a basis for modeling and mitigation and for understanding their flow behavior and dynamics. We still know relatively little about many aspects of landslide physics. It is only recently that the field of landslide dynamics is approaching a more mature stage. This is testified by the release of modelling tools for the simulation of landslides and debris flows. In this book the emphasis is placed on the problems at the frontier of landslide research. Each chapter is self-consistent, with questions and arguments introduced from the beginning.

This book was released on 2018-09-03 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the spatial distribution of landslide hazards of the Darjeeling Himalayas. Knowledge driven methods and statistical techniques such as frequency ratio model (FRM), information value model (IVM), logistic regression model (LRM), index overlay model (IOM), certainty factor model (CFM), analytical hierarchy process (AHP), artificial neural network model (ANN), and fuzzy logic have been adopted to identify landslide susceptibility. In addition, a comparison between various statistical models were made using success rate cure (SRC) and it was found that artificial neural network model (ANN), certainty factor model (CFM) and frequency ratio based fuzzy logic approach are the most reliable statistical techniques in the assessment and prediction of landslide susceptibility in the Darjeeling Himalayas. The study identified very high, high, moderate, low and very low landslide susceptibility locations to take site-specific management options as well as to ensure developmental activities in theDarjeeling Himalayas. Particular attention is given to the assessment of various geomorphic, geotectonic and geohydrologic attributes that help to understand the role of different factors and corresponding classes in landslides, to apply different models, and to monitor and predict landslides. The use of various statistical and physical models to estimate landslide susceptibility is also discussed. The causes, mechanisms and types of landslides and their destructive character are elaborated in the book. Researchers interested in applying statistical tools for hazard zonation purposes will find the book appealing.

Download or read book Modeling Gravity Hazards from Rockfalls to Landslides written by Vincent Richefeu and published by Elsevier. This book was released on 2016-10-11 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gravity hazards are a major concern to those living in mountainous areas. To protect infrastructure and human life in these areas, engineers require numerical tools for trajectory analysis, for application from fragmental rockfalls to large-scale avalanches or landslides.This book explores state-of-the-art methods to model the propagation (flows and stops) of masses, using the discrete element method (DEM) to study the evolution of kinetics during an event. Taking into account the shape of the blocks and the topology of the terrain provides an explicit and sophisticated consideration of geometries, eliminating the need for stochastic inputs to rockfall simulations. This method is validated experimentally, before the authors apply it to real case studies. The book ends with an introduction to and comparison with the material point method (MPM), a new and promising approach able to bridge the gap between cases dominated by discreteness and those involving a very large number of elements.Engineering consulting firms, researchers and students should find the approaches outlined in this book useful, whether designing prevention and protection systems for gravity hazards, or exploring new ways to model gravity hazards. - Covers conventional methods used to study gravitational phenomena using empirical parameters - Presents a new numerical tool taking account of the physical phenomenon (friction, dissipation, realistic block shapes) and a methodology for parameter calibration and the achievement of numerical simulations - Applies the numerical model to real cases with a critical analysis of its applicability in the field of engineering - Emphasizes the discrete element method (DEM)

Download or read book The Behavior of a Granular Flow from Collapsing to Spreading and Sliding Down a Frictional Incline written by Bahman Sheikh and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT Rapid flow-like landslides occur commonly in different parts of the world and present a serious threat to communities and infrastructures, especially in mountainous areas. Due to their high flow velocities, large impact forces, long-runout distance, and poor temporal predictability, flow-like landslides are among the major geohazards. Human safety and infrastructures can be endangered by large impact forces in unexpected flow-like landslide events. Hence, reliable estimates of the runout of flow-like landslides and their resultant impact force on structures are essential for both hazard assessment and the design of protective measures. However, it's challenging to capture, analyze and interpret the behavior of flow-like landslides as real full-scale observations and experiments are often difficult or impossible to conduct because of dangers involved with in-situ field experimental studies, uncontrollable geophysical conditions, and unpredictable time and locations of landslide events. Alternatively, scaled experimental studies of rapid debris flows can provide fundamental and valuable insights to better understand the underlying physics of landslides or to develop and validate a robust computational framework for landslide modeling. Although the scaled laboratory and field experiments of debris flow are useful, they cannot be directly utilized for landslide prediction and designs. Hence, a numerical model capable of simulating the debris flow and its interaction with structures, and reliably estimating the debris flow impact force would be an ultimate alternative for landslide designs. Numerical modeling of debris flow, however, is exceptionally complex since debris flow is known to exhibit both solid-like and fluid-like behaviors from grain inertia to micro viscous material which are responsible for the complex flow dynamics of debris flow. Therefore, numerical models capable of simulating the debris flow are naturally complex. Currently, most of the numerical methods proposed for modeling flow-like landslides or debris flows are developed by means of simplified relationships which are based on the assumption that the granular material is to behave like an incompressible fluid. These single-phase equivalent fluid models rely on manipulation of the rheological properties of landslide mass and, hence, have limited predictive power, and are mainly useful for modeling landslides runout, propagation and spreading which are mostly related to the fluid-like behavior of the granular flow. Solid-like behaviors of a sliding mass, however, can be inferred from its impact forces on a rigid obstruction. Therefore, a physically-based numerical model is required which is capable of taking into account the non-linear behavior of the granular material considering both fluid-like and solid-like behaviors, suitable for modeling of large displacement and deformation of the granular mass and taking into account frictional soil-structure interactions. Such numerical models need to be validated through systematic experimental studies at the well-controlled laboratory scale. In this research, the behavior of a granular sliding mass down an incline from collapsing, to sliding, and to impacting a rigid obstruction was investigated. The main objectives of this research are: (1) to develop and validate a computational framework capable of addressing the following four main challenges in landslide modeling and granular flow namely: (A) suitable for modeling of the large deformation of the granular material, (B) capable of considering the frictional soil-structure interaction, (C) equipped with suitable constitutive models to capture the complex behavior of a granular sliding mass in a rapid fluid-like landslide, and (D) computationally efficient to be practical for medium to large-scale granular modeling; (2) to study the governing mechanisms of granular collapse on a frictional surface; and (3) to study the governing mechanisms of granular flow and investigate the transition between solid-like and fluid-like behavior in a granular flow and its impact force. These research objectives are achieved by developing an efficient parallel numerical model based on the Smoothed Particles Hydrodynamics (SPH) method. Two frictional boundary conditions in the framework of SPH method were developed in this study and implemented into the SPH computational tool and their performance was examined in collisional and sliding problems. An elasto-plastic model, a critical hypo-plastic model and a collisional Bagnold-type rheology constitutive model were implemented in the SPH computational tool to investigate the granular flow impact force and mass front velocity. Results of this study revealed that the granular flow is governed by a combination of sliding, collapsing, and spreading mechanisms, depending on the inclination angle, sliding distance, basal friction, and the material initial condition. It is shown that the elasto-plastic models can predict the granular behavior and impact force relatively well in sliding-dominant flows only. The critical hypo-plastic model can consider the effect of dispersive pressure and shearing on the material stiffness and energy dissipation, it shows better predictions of the impact forces compared to the elasto-plastic model, especially in spreading-dominant flows. It is observed that the unified critical hypo-plastic and collisional Bagnold-type model predicted more accurate results of the impact force than the critical hypo-plastic model did, as the unified model accounts for both fluid-like and solid-like behaviors within a sliding granular mass.

Download or read book Geo disaster Modeling and Analysis An SPH based Approach written by Yu Huang and published by Springer. This book was released on 2014-08-22 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through application of the Smoothed Particle Hydrodynamics (SPH) method, this monograph mainly focuses on large deformations and flow failure simulations of geomaterials and movement behavior, which are always involved in geo-disasters. The work covers the theoretical background, numerical techniques, code implementation issues, and many novel and interesting applications. Two-dimensional and three-dimensional SPH models in the framework of both hydrodynamics and solid mechanics are established, with detailed descriptions. The monograph also contains many appealing and practical examples of geo-disaster modeling and analysis, including the fluidized movement of flow-like landslides, lateral spread of liquefied soils, and flow slides in landfills. In the documented SPH simulations, the propagation of geo-disasters is effectively reproduced. Dynamic behaviors of geomaterials during propagation are ascertained, including sliding path, flow velocity, maximum distance reached, and distribution of deposits. In this way, the monograph presents a means for mapping hazardous areas, estimating hazard intensity, and identifying and designing appropriate protective measures.
