Calculation for Permanent Displacement of Single Slip Surface of Multi-Stage Loess Slope Based on Energy Method

At present, there are still some gaps in the theoretical calculation of permanent displacement multi-stage loess slope under action earthquake. Therefore, this paper firstly uses GEO-Studio finite element software to explore influence comprehensive rate on when each grade changes and stage changes. The results show that it is feasible use calculate sliding body On basis conclusion, order simplify potential soil, other geometric parameters replaced by rate, combined with Newmark slider analysis method energy conservation principle, then soil earthquake deduced. Through an example, calculated proposed algorithm compared those PLAXIS 3D software. close software, difference only 2%, thus, rationality for calculating verified. provides a reference
