Abstract

Abstract

The dips of slices' force were determined by numerical simulation method by taking Monkey Stone landslide the study subject in this paper. The differences between the dips calculated by numerical simulation and those determined by the semi-precise slice method including the transfer coefficient method, Rohre law, the U.S. Army Corps of Engineers, simplified method and practical recursive method were analyzed. The effect of assumption of the slices' force dips based on semi-accurate slice method on the accuracy of landslide stability coefficient was discussed, and the results calculated by accurate slice method were compared with those calculated by numerical simulation. The study proves the accuracy and applicability of those current major semi-precision slice methods.
