既有铁路隧道渗漏水病害成因及对策

Causes and Countermeasures of Water Leakage in Existing Railway Tunnels

铁路的快速发展,使得铁路隧道迎来了空前的建设高潮。然而,绝大部分隧道在建造中及建成后存在不同程度的渗漏水问题,不仅会降低混凝土衬砌的耐久度,也会对各种既有设备的功能带来影响,给施工和运营团队带来不可预测的危险。从隧道的防水、排水设计系统、施工质量及防水材料的选择与使用等方面,系统地分析了隧道渗漏水的成因并提出相应的治理措施,确保隧道内部结构的安全和设备的正常使用。

With the rapid development of railway,railway tunnel has ushered in an unprecedented construction climax.However,most of the tunnels have water leakage problems in different degrees during and after construction,which will not only reduce the durability of concrete lining,but also affect the functions of various existing equipment,and bring unpredictable risks to the construction and operation team.This paper systematically analyzes the causes of tunnel leakage from the aspects of waterproof,drainage design system,construction quality and selection and use of waterproof materials,and puts forward corresponding treatment measures to ensure the safety of tunnel internal structure and normal use of equipment.
