Conventional methods of slope stability analysis can be divided into three groups: kinematic analysis, limit equilibrium analysis, and rock fall simulators. [10] Most slope stability analysis computer programs are based on the limit equilibrium concept for a two-or three-dimensional model.
Newmark analysis does not calculate actual displacement, but rather is an index value that can be used to provide an indication of the structures likelihood of failure during a seismic event. It is also simply called Newmark's analysis or Sliding block method of slope stability analysis.
Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement; the opposite condition is called slope instability or slope failure. The stability condition of slopes is a subject of study and research in soil mechanics , geotechnical engineering , and engineering geology .
The Sarma method is called an advanced and rigorous method of static and seismic slope stability analysis. It is called advanced because it can take account of non-circular failure surfaces. Also, the multi-wedge approach allows for non-vertical slices [5] and irregular slope geometry. [6]
UTEXAS is a slope stability analysis program written by Stephen G. Wright of the University of Texas at Austin. The program is used in the field of civil engineering to analyze levees, earth dams, natural slopes, and anywhere there is concern for mass wasting. UTEXAS finds the factor of safety for the slope
The developers of SVSLOPE have implemented all of the classic features traditionally found in slope stability software as well as an interesting list of new features. The following is a list of some of the more distinct features of SVSLOPE: Probabilistic analysis; One-way or two-way sensitivity analysis; Spatial variability using random fields
Rock mass classification systems are used for various engineering design and stability analysis. These are based on empirical relations between rock mass parameters and engineering applications, such as tunnels, slopes, foundations, and excavatability.
It has been extensively used in seismic analysis software for many years, although nowadays modern finite element analysis software are more widely used for special case studies. The Sarma method is called an advanced and rigorous method of static and seismic slope stability analysis. It is called advanced, because it can take account of non ...
