Calculation of Safety Factor of the Slope under Horizontal Seismic Forces Based on the Inclined Slice Method

Article Preview

Abstract:

The vertical slice method is generally adopted for calculation of slope stability safety factor. The algebraic expression of stability safety factor of the slope under horizontal seismic forces is deduced based on the idea of calculation via the inclined slice method and according to the force limit equilibrium conditions of inclined slices. It replaces conventional integral or differential expressions with advantages such as simplified calculation process, convergence performance guarantee and rapid calculation via simple iterative. The example shows that the slope stability safety factor derived from this method is very similar with that from conventional methods, which proves that this method is feasible and brings convenience to technical personnel of slope engineering.
