摘要
隧洞衬砌中将衬砌混凝土作为透水结构在工程中已经得到应用。南湃水电站引水隧洞采用该方法进行永久支护设计,特别是该水电站高压段围岩以Ⅲ类为主的情况下采用该方法为工程节约了工期和投资,取得较好的经济效益。目前该隧洞已经充水运行,状态良好。
In tunnel lining, the lining concrete as the permeable structure is applied in projects. This method is applied in Nam Phay Hydropower Project for design of the permanent support, shortening construction period, reducing investment and achieving better benefit as the surrounding rock at high-pressure section of the headrace tunnel of the Project is Class Ⅲ. Nowadays, the headrace tunnel operates with water charged and is in good status.
