| 摘 要： | 目前采用TBM开挖和预制管片衬砌的水工隧洞愈来愈多，其防渗效果如何是人们普遍关注的问题之一。文章在分析联接段7#隧洞输水渗漏损失量计算的同时，指出渗漏问题除同施工质量密切相关之外，衬砌构造的细部设计、工程地质和水文地质条件等也都有一定影响。

| Abstract: | Nowadays more and more hydraulic tunnels excavated by TBM and lined with precast duct pieces have been used, and its permeability- reducing result is one of the problems drawing people's attention commonly. Through analyzing on the calculation of the leakage loss of transmitted water of No.7 tunnel on linkage section, this paper points out that the leakage problem is not only relative to the construction quality, but also to the detailed design of lining structure, engineering geological and hydrographic conditions, etc. |
