Book excerpt: Master's Thesis from the year 2013 in the subject Engineering - Civil Engineering, grade: 3.74, Arba Minch University, language: English, abstract: Probabilistic methods of slope stability analysis accompanying conventional analyses provide the means for the reliability and probability of failure of the slope in a quantifying way. They provide us an important knowledge for stability condition of the slope. The essential requirement of the soil parameters is determined in the laboratory for the analysis of the slope meeting the insitu conditions. For the location of the phreatic surface three different scenarios were considered for the profile of the water surface to carry out the analysis. Effective strength parameters were considered to assess the long-term stability condition. The spatial variability of the random variables was incorporated into this model and by considering the contributions of the end resistance of 3-D probability of failure. The 3-D aspects of failure were investigated using FLAC3D software incorporating all the parameters of the soil to visualize the failure probability for the scenarios. Both normal and lognormal distribution of FOS were considered in order to compare and contrast the reliability and probabilities of failure in a measurable ways using NORMDIST and NORMSDIST program which is integrated in MS-EXCEL and from the probability density function table. The analysis gave that Probability of failure for normal distribution is higher than that of probability of failure for lognormal distribution. It was also attempted to investigate the best combination of the slope parameters to have the desirable target probability of failure for the scenarios and recommendation were made to provide geosynthetic reinforcement for stabilization and construct appropriate retaining wall with proper drainage as well as provision of sheet pile to achieve the desirable postulated probabilities of failure.

Book excerpt: This report is divided into eight sections and an executive summary. Section 3 presents various kinds of uncertainties in slope stability analysis and methods for handling these in the probabilistic slope stability methodology. A description of the model for performing probabilistic slope stability analysis is presented in Section 4 and the field program to develop the necessary probabilistic parameters is described in Section 5. A case study which utilized the methodology is reviewed in Section 6. Section 7 contains evaluations of the methodology by an independent consultant and by the Utah State University development team. Section 8 outlines additional case studies and development work needed to generalize the applicability of the methodology. Finally, the relationship of the methodology to an integrated risk assessment framework which considers all likely causes of slope failure is discussed in Section 9.
Download or read book Rainfall Induced Soil Slope Failure written by Lulu Zhang and published by CRC Press. This book was released on 2018-09-03 with total page 374 pages. 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 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stability of natural rock slopes is influenced by a wide spectrum of factors, such as mechanical properties of bedrocks and spatial distribution of discontinuities. Their specific values are typically incomplete, due mainly to the lack of effective and comprehensive methods to accurately characterize these factors, especially those inside of the slopes. The neutrosophic number is a useful tool to solve problems in indeterminate environment.

This reference book gives a complete overview of the developments in slope engineering in the last 30 years. Its multi-disciplinary, critical approach and the chapters devoted to seismic effects and probabilistic approaches and reliability analyses, reflect the distinctive style of the original. Subjects discussed are: the understanding of slope performance, mechanisms of instability, requirements for modeling and analysis, and new techniques for observation and modeling. Special attention is paid to the relation with the increasing frequency and consequences of natural and man-made hazards. Strategies and methods for assessing landslide susceptibility, hazard and risk are also explored. Moreover, the relevance of geotechnical analysis of slopes in the context of climate change scenarios is discussed. All theory is supported by numerous examples.

Book excerpt: In a probabilistic slope stability analysis, the input parameters are considered as random variables that must be statistically described. The descriptive process relies on statistical analyses of discontinuity data collected by field mapping and of laboratory and field test results. Sound geologic and engineering judgment should be used in conjunction with these analyses. The probability of stability for a given slope failure mode is estimated by combining the probability of sliding and the probability that the potential sliding surface is long enough to allow failure. The probability of sliding is calculated from a safety factor distribution which can be estimated by Monte Carlo simulation or by numerical convolution performed by discrete Fourier procedures. The probability of sifficient length is estimated from discontinuity length data obtained by structure mapping. Multiple occurrences of the same failures mode in a slope can be analyzed after they have been simulated by generating spatially correlated properties of discontinuities responsible for the failure mode. A probabilistic analysis also allows for the effects of different failure modes in the same slope to be combined into a probabilistic estimate of overall slope stability. Thus, rock slope engineering can be enhanced by probabilistic methods that allow for a realistic treatment of parameter variabilities and multiple failure modes and that also produce useful probabilistic slope design criteria.
