摘要
季节性冻土区运营铁路隧道渗漏水现象普遍存在,冬季渗漏水病害常演变为衬砌挂冰侵限、道床冻结上拱等病害,直接影响列车运营及隧道结构安全。渗漏水防治措施是目前国内外隧道设计、施工的重点和难点。本文通过分析铁路隧道渗漏水的原因,提出一种渗漏水综合防治措施,并详细介绍了整治方案的施工工艺,为类似工程提供参考。
Water leakage phenomenon of railway tunnel is common in seasonal frozen soil region,that evolve into ice covering of the lining,ballast freezing and other diseases in winter /which affect the operation of the train and tunnel structure safety directly.Prevention and regulation of water leakage is a key and difficult problem in design and construction of tunnel both in China and abroad.The cause of the leakage of the railway tunnel was analyzed to put forward a kind of leakage prevention measure,and provided a reference for similar project.
