Abstract
The authors propose the slope stability analysis method using the springs attached to the interslice plains based on the limit equilibrium method and discuss the application results. In this method (SSM), the slope is assumed to be a set composed of the rigid slices, elastic springs, and plastic sliders. The interslice forces are determined logically by the deformation of the vertical slices which are gotten from the stress-strain relation of the soil. The unique result of overall safety factor, a set of interslice forces, etc. are analyzed by using of this method. From the analytical results of the model slopes using the proposed method, it is clear that the safety factor, interstice forces, etc. agree approximately with the results of the Rigid Body Spring Method.
