季节性冻土区铁路隧道渗漏水原因分析及整治技术

摘要

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.%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.
