引起地铁车站渗漏水病害的施工因素分析

Analysis of construction factors causing leakage of metro station

明挖地铁车站在建设过程中会产生渗漏水病害问题,导致车站底板积水、结构开裂与溶蚀等病害,严重影响地铁车站结构的安全性。为此,针对地铁车站渗漏水病害成因中的施工问题,详细阐述了地铁车站混凝土施工因素中不同工艺参数引起渗漏水病害的作用机理与发展过程,并与现场试验数据进行了对比分析,研究结论为地下工程渗漏水病害处理提供了重要理论参考。

The problem of water leakage will be occurred in the construction of cut and cover subway station.These problems lead to water accumulation,structural cracking,corrosion and other diseases of the station floor and seriously affect the safety of subway station structure.Therefore,in view of the construction problems in the cause of subway station leakage,the mechanism and development process of water leakage caused by different process parameters in the concrete construction of metro station are described in detail,and compared with the field test data.The conclusion of the study provides an important theoretical reference for the treatment of the leakage of underground engineering.
