A new method of stability analysis of jointed rock slope

Zhongming Jiang

Abstract

The stability of jointed rock slope is controlled by shear strength of joints and rock simultaneously.Based on the instability failure mechanism of jointed rock slope with two sets of parallel joints,a new limit equilibrium method is studied;and the corresponding formulae for stability analysis are deduced.A program is developed for the validation of this method.Through the comparison between the results obtained from the new method and those from reference [4],it is shown that the new method for stability analysis of jointed rock slope is correct;and it is also an effective approach for the stability analysis for jointed rock slope with two sets of parallel joints.
