Stability Assessment of Multi-Stage Slopes Considering Local Failure

The analytical method for slope stability analysis requires a collapse mechanism in advance. multi-staged is generally assumed to be overall failure, whereas this kind of may suffer from local failure. However, failure rarely reported the previous research slopes, which result an overestimate stability. To end, incorporated into first time, so as develop complete approach assess multi-stage slopes. modified pseudo-dynamic conducted properly account seismic effects. Thanks limit and strength reduction technique, safety factor obtained. obtained by presented shows good agreement with that literature numerical calculations. slopes studied, schematically wide range parameters. results show often manifests under intense
