The high rock slope stability evaluation based on DDA

Zhao Binghua

Abstract

According to the classical damage problem of high rock slope,by use of DDA,the discontinuous deformation analysis(DDA) model is set up,combined with a rock edge slope engineering case of the highway.The relationship between joint parameters and slope deformation is studied,and the limited internal friction angle of the sliding face of slope is obtained under some conditions,the safety factor of slope stability is calculated,and the slope stability is evaluated.The results show that the actual situation with the basic agreement.
