摘　　要：锦屏一级水电站工程左岸抗力体布置了国际上水电建设史上地质条件最复杂、洞形最复杂的地下洞室群,过程中实现了成功开挖且无任何安全事故、投资控制良好的成功实例,特别是经锦屏一级水电站一次性蓄水至正常蓄水位证明,所确定的基础处理方案合理,处理效果良好。论文从工程项目管理、工程技术两方面对锦屏一级左岸抗力体成功开挖及灌浆进行了分析介绍,可为类似工程建设提供成功的经验。The left resistance rock of Jinping I Hydropower Station has arranged the underground caverns with the most complex geological conditions and the most complex caverns in the history of hydropower construction in the world.In the process,successful examples of successful excavation without any safety accidents and good investment control have been realized,especially by the one-time water storage to the normal water level of Jinping I Hydropower Station,it is proved that the basic treatment scheme is reasonable and the treatment effect is good.In particular,it is proved that the basic treatment scheme is reasonable and the treatment effect is good after the one-time water storage of Jinping I Hydropower Station to the normal water level.This paper analyzes and introduces the successful excavation and grouting of the left resistance rock of Jinping I Hydropower Station from the aspects of project management and engineering technology,which can provide successful experience for similar projects.
