| 摘 要： | 在反倾层状边坡内，开挖边坡并修筑隧道洞口后，出现岩体从隧道掌子面整体挤出和洞顶塌方现象，并导致边坡出现后缘拉裂、坡体内出现多处裂缝和岩块崩塌等坡体失稳迹象。通过对该边坡失稳和隧道塌方的勘察和机制分析，确定该坡体的变形破坏模式，提出针对性治理方案。

| Abstract: | 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 analyse 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. |
