夹岩水利枢纽工程隧洞施工期地下水监测、处理及补偿

Groundwater monitoring,treatment and compensation during tunnel construction of Jiayan Hydro-complex Project

夹岩水利枢纽工程地处贵州喀斯特发育地区,包含水源枢纽工程和输水工程两大部分,隧洞施工会遇到地下水处理问题,且容易对沿线居民生活用水造成影响。介绍了夹岩工程输水区隧洞施工期地下水监测、废污水处理措施及对居民饮用水影响补偿,分析了隧洞施工图阶段对比初步设计阶段隧洞地下水处理投资变化原因,提出了加强涌水及废污水处理监测等建议,可为类似工程隧洞施工地下水处理提供参考。

The Jiayan Hydro-complex Project is located in karst area of Guizhou Province.The project consists of water source project and water conveyance project.There were problems in the groundwater treatment during the tunnel construction,which would affect the drinking water of residents along the line.The groundwater monitoring,wastewater treatment measures and compensation for impact of drinking water during tunnel construction period in the water diversion area were introduced.The reasons for the changes of groundwater treatment investment in the tunnel construction drawing stage were analyzed comparing with the investment in the preliminary design stage.The suggestions such as enhancing water gushing and wastewater treatment monitoring were put forward,which can pro⁃vide a reference for similar projects.
