水利枢纽沿线堤防的加固,是构成水库总体稳固的根基。在修建规模偏大的水库时,水库沿线隧道特殊地质段的建设问题是工程的关键问题。文章针对商洛县张坪水库引水隧道施工遇到的情况,介绍了水利枢纽隧道工程所处的特殊地质环境,分析了隧道施工中存在的问题,提出断面层管控加固施工方案,通过3种管控加固方案的分步实施,有效加固了隧洞围岩的断层面,在隧道后期施工过程中取得了很好的稳固效果。

Reinforcement along the dike project constitutes the foundation of reservoir total stability.When a large-scale reservoir is built,construction of special geological sections along the reservoir tunnel is the key engineering.According to the situation encountered in construction of diversion tunnel of Zhang Ping reservoir,Shangluo County,the special geological environment of tunnel engineering water conservancy hub is introduced,the existing problems are analyzed in the construction of tunnel,put forward the construction scheme of fault plane hierarchical control and reinforcement.Through three kinds of hierarchical control and reinforcement schemes step by step,the fault plane of the surrounding rocks is reinforced effectively and good stable effect is achieved at the later construction of the tunnel.
