Factors that Causing the Tunnel Liner Leakage and Its Mitigation

隧道在使用过程中会出现变形缝处渗漏水、侧墙墙面渗漏等现象。在某铁路隧道渗漏水整治的工程过程中,通过定量调查统计,定性分析隧道渗漏水形成的原因,提出不同处理方案:混凝土表面湿渍及渗漏水区处理、施工缝渗漏水处理等,供类似工程参考。

It is very usual to observe the water leakages at the deformation joints and side walls during the tunnel operations after the construction. This paper presents a case history of a tunnel liner leakage mitigation details. The factors that causing the liner leakage are presented from both the statistically investigation and the qualitative analyses, The different mitigation methods for the different leakages, such as, water marks at the concrete surface, leakage at the liner through the groundwater rich areas and the seepage at the construction and deformation joints, are proposed in the paper.
