河口村水库泄洪洞进口位于山岩褶皱断裂发育区,其左侧边坡断层节理发育,对边坡安全稳定影响较大。文章根据现场开挖揭露的实际地质条件,运用刚体极限平衡原理,参照《水利水电工程边坡设计规范》,对断层、裂隙组合剪切的楔形体模型进行稳定安全计算,提出布置锚索加固措施方案,取得较好效果。 The entrance to the spillway tunnel of Hekou Village Reservoir is located in the fold rock development zone of Shanyan, and the fault joints of the left slope are developed, which have a great influence on the safety and stability of the slope. According to the actual geological conditions exposed by on-site excavation, the rigid-body limit equilibrium principle is used to calculate the stability and safety of the wedge-shaped model combined with shear faults and fissures according to the Code for Design of Slope Design of Water Conservancy and Hydropower Engineering Program, achieved good results.
