A finite-element-based numerical simulator in the Phase2 software program was used to generate the critical shear SRF, which is equivalent to the FoS. To back-analyze multiple sets of slope stability parameters simultaneously under uncertainty, the back-analysis can be Jan 25, 2011 · PDF | This paper presents a simplified three-dimensional (3D) slope stability analysis method based on the limit equilibrium theory. slope stability ensuring. Burman, S. This is the reason that so many analysis techniques have been developed so far. 1139 Jan 6, 1995 · A stability analysis of slopes based on a translational mechanism of failure is presented. , mechanism of the slope failure e, numerical Nov 4, 2022 · The purpose of this article was to investigate the influence of uncertain soil parameters on slope stability problems using the probability method. By equating the work done by external loads and body forces to the energy dissipated in shearing, either a Feb 12, 2021 · A statically accurate limiting equilibrium procedure is developed for the numerical treatment of nonhomogeneous earth slopes. These procedures are discussed in Chapter 13. 3 Geometry and Soil Parameters In this study, a slope with an inclination angle of 26,56° (2:1) to the horizontal plane and a height of 50 m was considered (Fig. 2226, respectively. 1803. Due to its complexity and nonlinearity involved in the evaluation process, it cannot provide a quick stability estimation when facing a large number of slopes. The data set of this study Dec 31, 2019 · Rock slope stability assessment is basically used for designing and evaluating the slope stability of the rock and mean while this is used for safety of the mine site. Compared with traditional methods May 15, 2014 · In this paper, two drawbacks of the traditional pseudo-static method (vertical slice method) in the slope stability evaluation have been studied. This was not the outcome envisaged when Whitman & Bailey (1967) set criteria for the then emerging methods to become readily accessible to all engineers. e. 1. The results showed that equivalent area circle D - P yield criterion was suitable for slope stability analysis and that strength reduction technology could be applied in simple homogeneous side slope stability analysis. embankments, road cuts, open- pit mining, excavations, landfills etc. 78 for analyzed cases. 2. The problem of slope stability is processed theoretically and parametrically - parametrical study. The input parameters used for the slope stability analysis are presented in Table 2. Each stability analysis method differs from the others in some of the basic assumptions, but most of these Apr 21, 2016 · The importance of 3D analysis of slope stability is greatly increased where the geometry is complex which makes it difficult to select a typical section for 2D analysis. cohesion, friction and unit weight are developed in this paper. C, Nowatzki, E. In limit equilibrium techniques, slope stability is analyzed by first computing the factor of safety. Jan 25, 2023 · Earth slopes’ stability analysis is a key task in geotechnical engineering that provides a detailed view of the slope conditions used to implement appropriate stabilizations. Several computations can be carried out for a single task. Since 1990s, a lot many number of three-dimensional slope stability-analysis methods were developed based on limit equilibrium and finite element concept. Aug 27, 2019 · In the 2D limit analysis of slope stability, the slope is presumed to be infinitely wide along the out-of-plane direction, negating the 3D effects caused by the infinite width of sliding mass. The proposed P-CSIM is used to solve the Richards’ equation for the slope, then the numerical solution of the pressure head is substituted into the infinite slope model, and the stability of the slope is analyzed. Oct 18, 2022 · Although slice methods are simple and effective slope stability analysis approaches, they are statically indeterminate. The analysis will be conducted in Slide2 v6. Apr 13, 2021 · The strength reduction method (SRM) is one of the main methods for evaluating slope stability and its key step is to select failure criteria reasonably and correctly. At Kaliasaur landslide (site Dec 10, 2023 · During heavy rainfalls, slope stability issues and rainfall-induced failures are often encountered (Chatra et al. . P. May 2, 2018 · The importance of three-dimensional (3D) slope stability analysis greatly increased where the geometry of the problem becomes complex which makes it very difficult to solve using 2D analysis. Correlations between Factor of Safety (FS) and soil parameters i. 2604, and also the dynamic analysis 1.
