东湖湖底隧道运营期渗漏治理技术

东湖湖底隧道不同于一般隧道工程,由于其所处的环境具有一定的特殊性,长期处于水下环境。隧道在运营过程中,受各种因素影响,渗漏已成为影响隧道正常运营的主要原因之一。东湖湖底隧道渗漏的原因主要有自然因素和非自然因素,非自然因素包括设计因素和施工因素。隧道渗漏的类型有结构缝渗漏、施工缝渗漏、变形缝渗漏以及蜂窝面渗漏四种类型。根据不同渗漏的类型,提出相应的治理技术,保障隧道正常运营,减少其社会影响。在管理上,还应该建立日常的渗漏排查机制。

The Donghu Lake bottom tunnel is different from the general tunnel engineering;because of its special environment,it has been in the underwater environment for a long time.In the process of tunnel operation,affected by various factors,leakage has become one of the main factors affecting the normal operation of the tunnel.The leakage of Donghu Lake bottom tunnel is mainly caused by natural factors and non natural factors,including design factors and construction factors.There are four types of tunnel leakage:construction joint leakage,structural joint leakage,deformation joint leakage and honeycomb surface leakage.According to different types of leakage,the corresponding treatment technology is proposed to ensure the normal operation of the tunnel and reduce its social impact.We should also establish a daily leakage investigation mechanism in terms of management.
