摘　　要：加固复杂的岩体边坡,需要对不稳定岩体及其相互之间的关系进行准确判断和计算分析,采取有效的工程措施和合理的设计方案。双沟导流洞进口边坡在开挖过程中突然产生塌滑,边坡岩体被洞口和断层以及纵横交错的裂隙切割,形成了复杂的空间不稳定滑移体系,有进一步塌滑可能。为此,本文采用双滑面滑动机理进行抗滑稳定分析,由计算结果给出了锚索空间加固体系设计方案,同时辅以安全监测手段,较好地解决了边坡安全稳定问题,保证了主体工程工期。The relations between unstable blocks and key blocks in the complex sloping rock mass should be accurately considered. Therefore, we could effectively design the reinforcement and the engineering project. The sloping rock mass of water-diversion tunnel in Shuanggou Power Station had been cut into unstable landslide systems by faults and fissures, and suddenly fallen during excavation. Considering that the sloping rock mass would collapse furthermore, the design of pre-stressed anchor of reinforce system was conducted by the sliding mechanism with double slip surfaces and slope stability analysis. In fact, the stability of sloping rock mass was effectively kept and the river closure in construction stage was ensured.
