合福铁路楼村隧道渗漏水成因分析及防治技术

Causing analysis and prevention technologies for Loucun tunnel water leakage of Hefei-Fujian Railway

隧道渗漏水会严重影响隧道的正常施工以及安全运营。文章分析了当前隧道渗漏水现状,结合楼村隧道的工程地质情况,采用层次分析法对楼村隧道渗漏水产生的各影响因素进行了计算分析,结果显示主要因素为隧道防排水施工设计以及当地年降雨量,并总结了相应的防治技术。

The tunnel water leakage affects the tunnel construction and safe operation seriously. We analyzed the current status of the tunnel water leakage. Based on the engineering geology of Loucun tunnel, we analyzed the influence factors causing the water leakage by using AHP. The results shows the main factors causing the problem of water leakage are the drainage design and construction of Loucun tunnel and the local annual rainfall, and the corresponding prevention technologies are summarized.
