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.

Download or read book Guidelines for Probabilistic Performance Based Seismic Design and Assessment of Slope Engineering written by Yu Huang and published by Springer Nature. This book was released on 2023-03-16 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a new design and evaluation framework based on slope Stochastic Dynamics theory to probabilistic seismic performance for slope engineering. For the seismic dynamic stability safety of slope, it shifts from deterministic seismic dynamic analysis to quantitative analysis based on nonlinear stochastic dynamics, that is, from qualitative to the description of stochasticity of earthquake excitation that meet the needs in related design specification and establish a performance standard. In the nonlinear dynamic time history analysis of slope subjected to seismic ground motion, the term “randomness” is used to express the uncertainty in the intensity and frequency of earthquake excitation for slope engineering dynamic seismic performance. It mainly includes seismic design fortification standard, corresponding ground motion excitation, performance index threshold, and slope deterministic nonlinear seismic dynamic response. Even more than that, the seismic dynamic large deformation approaches of the whole process and comprehensive analysis for flow analysis after slope instability failure. Eventually, the probabilistic seismic dynamic performance of the slope engineering will be characterized by nonlinear dynamic reliability.

Download or read book Slope Stochastic Dynamics written by Yu Huang and published by Springer Nature. This book was released on 2022-02-02 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a new framework for analysis of slope nonlinear stochastic seismic dynamic response based on the new theoretical tool of stochastic dynamics. The coupling effects of uncertainty of geological parameters, strong dynamic nonlinearity, and randomness of ground motion are considered in the process of the seismic dynamic stability assessment of slope. In this book, an intensity frequency non-stationary stochastic ground motion model based on time-domain stochastic process description is preliminarily established to characterize the randomness of earthquakes. The spatial distribution random field model of geotechnical parameters is established to describe the time-space variability of geotechnical parameters. Based on the basic theory of stochastic dynamics, the seismic stability performance evaluation method of slope is established. The slope seismic dynamic model test based on large complex shaking table is performed to verify and modify the proposed framework and method. This book sheds new light on the development of nonlinear seismic stochastic dynamics and seismic design of slope engineering.

The previous volume can be found here: Spatial Modelling and Failure Analysis of Natural and Engineering Disasters through Data-based Methods - Volume II and Spatial Modelling and Failure Analysis of Natural and Engineering Disasters through Data-based Methods Natural and engineering disasters, which include landslides, rock fall, rainstorm, dam failure, floods, earthquakes, road and building disasters and wildfires, appear as results of the progressive or extreme evolution of climatic, tectonic and geomorphological processes and human engineering activities. It is significant to explore the failure mechanism and carry out spatial modeling of these engineering and natural disasters due to their serious harm to the safety of people's lives and property. The data-based methods, including advanced and successful remote sensing, geographic information systems, machine learning and numerical simulation techniques methods, are promising tools to analyze these complex disasters.

Download or read book Prevention Mitigation and Relief of Compound and Chained Natural Hazards written by Chong Xu and published by Frontiers Media SA. This book was released on 2024-08-21 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the intensification of global climate and environmental change has led to frequent occurrence of natural hazards. Various types of natural hazards always overlap and interact, or occur in a chain reaction, with a wide range of impacts and a long period of time, resulting in serious disaster losses. Typically, major earthquakes and geological hazards, extreme meteorological hazards, large-scale floods and droughts, marine disasters, and forest and grassland fires, as well as their compound and chained hazards are among the key factors affecting human life safety and world economic development. To better our understanding of disaster prevention, mitigation, and relief, it is thus pivotal to facilitate advanced perception, intelligent early warning, accurate prevention, and efficient rescue of natural hazards. This Research Topic aims to collect both Original Research and Review articles addressing the state-of-the-art advances of theories and methodologies in all types of natural hazards. Studies underlining the compound and chained relationship between different hazards are in particular welcomed. Potential themes include, but are not limited to: • Mechanisms of formation, evolution, and disaster process of multiple natural hazards as well as their compound and chained natural hazards • Model and scenario development regarding whole process control, chain breaking of key nodes, and precise prevention of major natural hazard chains • Methods and applications on detection, identification, database establishment, and spatiotemporal evolution law analysis of natural hazard sources • Technologies on intelligent early warning and refined risk assessment of compound and chained natural hazards. • Rescue equipment and investigation of post-disaster community reconstruction

Download or read book Modeling Spatial and Economic Impacts of Disasters written by Yasuhide Okuyama and published by Springer Science & Business Media. This book was released on 2004-05-18 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a collection of innovative papers on strategies for analyzing the spatial and economic impacts of disasters. Natural and human-induced disasters pose several challenges for conventional modeling. For example, disasters entail complex linkages between the natural, built, and socio-economic environments. They often create chaos and economic disequilibrium, and can also cause unexpected long-term, structural changes. Dynamic interactions among agents and behavioral adjustments in a disaster become complicated. The papers in this volume make notable progress in tackling these challenges through refinements of conventional methods, as well as new modeling frameworks and multidisciplinary, integrative strategies. The papers also provide case study applications that afford new insights on disaster processes and loss reduction strategies.
