隧道二衬厚度不足的原因和防控对策——以当金山隧道为例

Causes of Insufficient Thickness of Tunnel Secondary Lining and Countermeasures for Prevention and Control——Take Dangjinshan Tunnel as an Example

在隧道工程施工建设中,受水文地质等因素的影响,存在着隧道二衬厚度无法达到设计要求的情况。为此,文章应用案例分析法,以当金山隧道为研究对象,针对当金山隧道二衬厚度不够的原因进行深入分析和讨论,并根据隧道施工过程中存在的实际问题提出解决措施,希望能促进我国隧道工程的快速发展。

In the construction of tunnel engineering, due to the influence of hydrogeology and other factors, there is a situation that the thickness of the second lining of the tunnel can not meet the design requirements. To this end, taking Dangjinshan tunnel as the research object, this paper uses case analysis method to conduct in-depth analysis and discussion on the reasons for the insufficient thickness of the secondary lining of Dangjinshan Tunnel, and puts forward solutions according to the actual problems existing in the tunnel construction process, hoping to promote the rapid development of tunnel engineering in China.
