摘　　要：多数山区铁路隧道存在渗漏水病害,不同程度地影响列车运行。尤其冬季,渗漏水常演变为衬砌挂冰、道床冻结等次生灾害,危及行车安全,影响隧道设备设施健康服役。通过分析既有铁路隧道渗漏水的发生部位、表现形式、病害类别,从设计、施工和养护维修等层面探究其成因,提出新的渗漏水整治措施,对延长既有线铁路隧道使用寿命、保障行车安全具有借鉴意义。Leakage diseases exist in most mountain railway tunnels,which affect the train operation to varying degrees.Especially in winter,the leakage often evolves into secondary disasters such as lining icing and ballast bed freezing,endangering traffic safety and affecting the healthy service of tunnel equipment and facilities.Based on the analysis of the occurrence site,manifestation and disease type of tunnel leakage of existing railways,this paper explores the causes from the aspects of design,construction and maintenance,and puts forward a new leakage treatment measure,which has reference significance for extending the service life of the railway tunnel on existing railways and ensuring traffic safety.
