Searching for multistage sliding surfaces based on the discontinuous dynamic strength reduction method

A loose slope structure and multiple free faces in a step-like landform are important engineering geological factors that cause multistage landslides. Tensile cracks that develop inside the slopes and the free faces created by excavation will have an impact on determining the location of potential multistage sliding surfaces. However, it is difficult to accurately locate sliding surfaces with tensile cracks in multistage landslide stability...
