摘　　要：水害是西南岩溶地区运营铁路隧道较常见的灾害,后果一般较为严重。针对某岩溶隧道突涌水灾害进行了成因分析,制定了针对性的整治方案,表明地下水侵蚀、不良地质作用及隧道防排水系统失效是该隧道水害产生的主要原因,采用增设排水洞和集水廊道、对衬砌背后溶腔处理等处治技术措施,有效解决了隧道水害问题,可为类似工程问题提供借鉴。Water inrush is a common disaster in operating railway tunnels in karst areas of southwest China,the consequences are generally serious.In this paper,the causes of a tunnel water inrush disaster is analyzed for a karst tunnel,and a targeted remedied program is formulated.It is shown that the groundwater erosion,adverse geological effects and tunnel drainage system failure are the main causes of the disaster.Water inrush is effectively solved by the treatment technologies of additional drainage holes,water collection corridors,the cavity disposal behind the lining.These technologies effectively solve the water disaster problems,which can provide reference for similar engineering problems.
