摘要
In anti-dip within the layered rock slope, the phenomenon of the rock mass being forced out entirely from tunnel working face and the hole supports landslide will turn up after excavating side slope and constructing the entrance to tunnel. It leads to the instability of slope body, such as the breakage of trailing edge in the side slope, the cracks and Collapse of rock in Slope body. According to the survey and analyze to the slope instability and tunnel collapse, The article has ascertained the pattern of deformation and breakage of the slope body and have raised a scheme to govern it.
