盾构隧道渗漏水原因及危害研究综述

渗漏水病害已成为目前我国盾构隧道的主要问题之一。研究隧道渗漏水的原因与危害,有助于进一步解决渗漏水问题。根据现有研究成果,对盾构隧道渗漏水的原因与危害进行了总结与归纳,从施工前、施工期间以及工后三个阶段对隧道渗漏水原因进行了分析,将渗漏水模拟方法归纳为等效渗流和接头渗漏;从渗漏水引起的土体孔压分布、隧道沉降和土体(包括地面)沉降等方面对管片渗漏水危害进行了分析。最后提出了现有研究的不足之处,并对盾构隧道渗漏水研究提出了一些建议。

A REVIEW OF THE CAUSES AND HAZARDS OF SHIELD TUNNEL LEAKAGE

The leakage of water has become one of the main problems of shield tunnel in China.Studying the causes and hazards of tunnel leakage water can help to solve the problem of leakage water.Based on the existing research results,the causes and hazards of the leakage of shield tunnel are summarized and summarized.The causes of tunnel leakage are analyzed from the pre-construction,the construction period and the working stage.The method is summarized as equivalent seepage and joint leakage.The hazard of the seepage of the seepage is analyzed from the pore pressure distribution,the settlement of the tunnel and the settlement of the soil (including the ground).Finally,the shortcomings of the existing research are put forward,and some suggestions are put forward for the study of shield tunnel leakage.
