摘　　要：水利水电工程开挖形成的人工边坡一般具有高差大、坡面陡峻、地质条件复杂、处理难度高、边坡失稳带来的危害大等特点。针对雅砻江杨房沟水电站左岸坝肩f27断层的工程地质性状,分析和评价该断层对边坡稳定性的影响,提出相应的治理方案。对锚索体结构提出多重防护措施,在水电工程领域尝试开展了基本验收试验。实施后经过变形监测反馈证明,边坡处于稳定状态。In many hydropower projects,artificial slopes have large elevation differences,steep slopes and complicated geological conditions,which bring great difficulties to slope reinforcement engineering.The engineering geological characteristics of the f27 fault on the left bank of Yangfanggou Hydropower Station in Yalong River are described in detail,the influence of the fault on the slope stability is analyzed and evaluated,and then,a corresponding treatment plan is proposed. After slope reinforcement,the deformation monitoring feedback proves that the slope is in a basically stable state.
