Seismic reliability analysis of soil slope based on Newmark sliding block model with representative slip surfaces and response surfaces

This paper presents a framework combining Monte Carlo Simulation (MCS) and the Newmark sliding block model with representative slip surfaces (RSS) (model II) multiple response method (MRSM) to conduct seismic reliability analysis risk assessment of soil slopes. An empirical threshold is introduced define limit state function identify failure samples in MCS area displacement are multiplied quantify consequence. The proposed methodology illustrated through slope layers. calculation results demonstrate that traditional I) tend underestimate variations yield acceleration. Both probability landslide exhibit decreasing trends increase threshold. Significant discrepancy between two models found even for small Therefore, highly recommended assessment. contributions RSSs insensitive variation thresholds.
