| 摘 要： | 分别运用有限差分法对边坡整体和块体极限平衡法对边坡局部进行稳定性评价.结果表明,局部的小断层对该边坡的整体稳定没有构成较大威胁,但部分含有断层的区域应该给予重点关注;边坡开挖后整体的位移和拉应力区域较小,应根据需要进行加固;在430-460 m高程开挖施工过程中,形成的开挖剖面可能与两组结构面组成不稳定块体,故应重视开挖方向和顺序;开挖完成后两组结构面距离下游开挖面较远,组成不稳定块体的可能性不大,但施工中应做好排水措施. |

| Abstract: | The overall and local stabilities of slope are analyzed by finite difference method and block limit equilibrium theory respectively for a hydropower project.The results show that:(i) Local small faults do not pose a greater threat to the overall stability of slope,but some of areas which containing faults should be focused;(ii) The areas of displacement and tensile stress after excavation are smaller and should be reinforced as needed;(iii) In the excavation of the area between El.430-460 m,the excavation p... |
