Abstract: Abstract of thesis entitled Study of Pullout Behaviour of Soil Nails in Completely Decomposed Granite Fill Submitted by Bandana Pradhan for the degree of Master of Philosophy at The University of Hong Kong in August 2003 Soil nailing is a technique for reinforcing slopes by installing closely spaced passive slender inclusions into the soil to increase its shear strength. It has been extensively used in slopes comprising in-situ or compacted soils. However, its uses in slopes comprising loosely compacted or uncompacted fill slopes are limited, because there is a lack of quantitative understanding of the behaviour of soil nails in such fills. A laboratory study of pullout resistance of grouted soil nails was therefore conducted to investigate the behaviour of soil nails in completely decomposed granite (CDG) soil fill. Pullout tests were carried out in a large test box (length 2m width 1.6m height 1.4m). The vertical pressure was varied by means of hydraulic jacks. During the tests the degree of compaction and degree of saturation were also varied. The study focused on the development of pullout resistance of soil nails during the pullout, and the soil-nail interface characteristics, especially in loose fill at natural moisture content. The peak pullout force and the pre-peak and post-peak load-displacement behaviours were established by pulling the nails in displacement-rate controlled manner. The results of the study indicate that the pullout load-displacement curves have distinct peak values, followed by a reduction in the post-peak stage both in loose and dense fills. A large portion of the pullout resistance is mobilized within a very small displacement. There is an increase in the pullout resistance as the overburden pressure and the degree of compaction increase. The apparent soil-nail interface friction angles are very close to the friction angles of the soil. However, the apparent interface adhesion depends on the degree of saturation and the degree of compaction of the soil.

Available in PDF, EPUB and Kindle. Book excerpt: This book, with contributions from international landslide experts, presents in-depth knowledge of theories, practices, and modern numerical techniques for landslide analysis. Landslides are a reoccurring problem across the world and need to be properly studied for their mitigation and control. Due to increased natural and anthropogenic activities, chances of landslide occurrence and associated hazards have increased. The book focuses on landslide dynamics, mechanisms and processes along with hazard mitigation using geo-engineering, structural, geophysical and numerical tools. The book contains a wealth of the latest information on all aspects of theory, practices and modelling tools and techniques involved in prediction, prevention, monitoring, mitigation and risk analysis of landslide hazards. This book will bring the reader up to date on the latest trends in landslide studies and will help planners, engineers, scientists and researchers working on landslide engineering.

Download or read book Soil Nailing written by Raymond Cheung and published by CRC Press. This book was released on 2021-03-11 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil nailing is an in situ soil reinforcement technique that can be used to enhance the stability of slopes, retaining walls, embankments, and excavations. It involves installation of closely spaced, relatively slender unstressed tension-carrying structural elements into the ground to stabilize the soil mass. These elements, which are called soil nails, comprise steel or other engineering materials such as fiber reinforced polymer. Soil nailing did not gain popularity until the 1970s when engineers started to realize that the technique could offer an effective, robust, and economical reinforcing system for a variety of ground conditions. More importantly, the track record has been excellent in that no major collapses have been reported in properly designed and well-constructed soil nailed structures so far. Considerable experience and knowledge of the technique have been gained in the past few decades through systematic technical development work comprising laboratory tests, numerical modeling, physical modeling, site trials and field monitoring covering design, and construction practices. Soil Nailing: A Practical Guide consolidates the experience and advances made in the development and use of the soil nailing technique and encourages a wider adoption of the technique by practitioners. The book is intended for use by postgraduate students, researchers, and practicing civil and geotechnical engineers, who wish to have a more in-depth and fundamental understanding of the theory and practice behind the technique. It presents the basic principles of the technique as well as state-of-the-art knowledge and recommended standard of good practice in respect of design, construction, monitoring, and maintenance of soil nailed structures.

Available in PDF, EPUB and Kindle. Book excerpt: Rainfall-induced landslides are common around the world. With global climate change, their frequency is increasing and the consequences are becoming greater. Previous studies assess them mostly from the perspective of a single discipline—correlating landslides with rainstorms, geomorphology and hydrology in order to establish a threshold prediction value for rainfall-induced landslides; analyzing the slope’s stability using a geomechanical approach; or assessing the risk from field records. Rainfall Induced Soil Slope Failure: Stability Analysis and Probabilistic Assessment integrates probabilistic approaches with the geotechnical modeling of slope failures under rainfall conditions with unsaturated soil. It covers theoretical models of rainfall infiltration and stability analysis, reliability analysis based on coupled hydro-mechanical modelling, stability of slopes with cracks, gravels and spatial heterogenous soils, and probabilistic model calibration based on measurement. It focuses on the uncertainties involved with rainfall-induced landslides and presents state-of-the art techniques and methods which characterize the uncertainties and quantify the probabilities and risk of rainfall-induced landslide hazards. Additionally, the authors cover: The failure mechanisms of rainfall-induced slope failure Commonly used infiltration and stability methods The infiltration and stability of natural soil slopes with cracks and colluvium materials Stability evaluation methods based on probabilistic approaches The effect of spatial variability on unsaturated soil slopes and more

This book was released on 2020-11-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces systematically the application of Bayesian probabilistic approach in soil mechanics and geotechnical engineering. Four typical problems are analyzed by using Bayesian probabilistic approach, i.e., to model the effect of initial void ratio on the soil–water characteristic curve (SWCC) of unsaturated soil, to select the optimal model for the prediction of the creep behavior of soft soil under one-dimensional straining, to identify model parameters of soils and to select constitutive model of soils considering critical state concept. This book selects the simple and easy-to-understand Bayesian probabilistic algorithm, so that readers can master the Bayesian method to analyze and solve the problem in a short time. In addition, this book provides MATLAB codes for various algorithms and source codes for constitutive models so that readers can directly analyze and practice. This book is useful as a postgraduate textbook for civil engineering, hydraulic engineering, transportation, railway, engineering geology and other majors in colleges and universities, and as an elective course for senior undergraduates. It is also useful as a reference for relevant professional scientific researchers and engineers.
