| 摘 要： | 锦屏一级水电站左岸高边坡F42-9断层及煌斑岩脉组合的滑块对左岸缆机平台及拱肩槽边坡的稳定性起到控制性的作用。针对F42-9断层两侧平行结构面的发育程度，进行了锚固边坡开挖过程中的弹塑性力学行为分析。结果表明：平行于F42-9断层发育的结构面使锚固边坡岩体的性状急剧下降，现有的加固方案无法满足边坡稳定性的要求。建议根据边坡及抗剪洞开挖过程中揭露的地质信息，及时制定合理的边坡加强、加固措施。

| Abstract: | The sliding zone made up of fault F42-9 and lamprophyre controls the stability of left cable-machine slope and arch dam abutment slope at Jinping First Stage Hydropower Station.The elastoplastic mechanism about reinforcement slope during excavation is simulated based on the occurred texture planes parallel to fault F42-9.The analytical results show that the designed reinforcement scheme can not ensure slope stability because of the sharply decreasing with rock mass behavior when the texture planes parallel ... |
