Burgess, Jesse2016-04-282016-04-282016-04-28http://hdl.handle.net/10222/71519Deterministic slope stability design charts for cohesive-frictional (c-φ) soils have been used by geotechnical engineers to examine the effects of earthquakes on slopes by identifying the critical seismic loading which brings the slope to a state of limit equilibrium. However, seismic slope stability design charts have yet to be extended to probabilistic analysis. In this study, the seismic stability of slopes, modeled using a two-dimensional spatially random c-φ soil, is studied using finite element analysis. Probabilistic analyses of seismically loaded slopes are performed by Monte Carlo simulations using the Random Finite Element Method (RFEM). A series of new slope stability design charts are provided that consider the influence of the spatial variability of soil for seismically loaded slopes with φ = 20°. The charts may be used in the safe design of slopes subject to seismic loading, providing estimates of the probability of slope failure without requiring computer simulations.enRFEMSeismicProbabilistic analysisDesign ChartsSlope stabilitySpatial variabilityCohesive-frictional
