摘要
尾水调压室是比较典型的埋深大、高边墙、特大断面地下洞室,在顶拱开挖时局部掉块严重。基于工程地质理论和块体理论综合分析后,认为对该不稳定块体应采取相应的支护措施,并应进行监测,必要时采取强支护措施。
Tailrace surge tank has following typical characters：deep embedding,high wall,large section, During the excavation, failing of rock blocks often occurred. After analyzing with engineering geological theory and block theory,support measures should be adopted. And geological condition should be examined with progress of work , stronger supporting must be used when it is needed.
