Abstract:There are alternative stratified joint groups in a stratified rock slope. According to the relation of angles of joints and the slope,stratified rock slopes can be divided into three types:horizontal slopes,reversely inclined slopes and rock bedded slopes. Among these three types of slopes,the rock bedded slopes are most likely to slide. A kind of geo-model material is used to model the bedding slope in this paper. The failure behaviors of cutting slopes in layered rock mass are analyzed by multi-stage excavation of the slope. At the same time,FLAC3D program is used in the model of damage process. The results from the two methods are well coincident. The results show that,in order to avoid the failure of the slope,excavating and supporting should be carried out simultaneously,and anchor bolts should be used firstly in the foot of the slope.
