摘　　要：在复杂地质区,为了科学地确定不同隧道穿越方式下的集水面积,本文以地形、岩性、地质构造3因素为基础构建不同的地质结构,结合隧道空间展布的变化对集水面积进行研究。归纳、总结了3类主要汇水地形、4类地质结构和2类隧道穿越方式。综合上述因素,总结出埋藏-向斜式、埋藏-背斜式、埋藏-单斜式和裸露-单斜式4种集水面积变化模式,同时得出不同模式中集水面积的确定方法。以渝利铁路箭沱湾隧道为例进行分析研究,得出隧道涌水量计算中集水面积属于第Ⅱ类模式,隧道穿越埋藏式地层,判断隧道集水面积时容易忽略部分面积,应加以重视。The different geological structures are established in terms of topography,lithology and geological structure;the catchment area is studied based on the variation of the spatial distribution of tunnel;and the kinds of main catchment topographies,geological structures and tunnel crossing modes are summarized.The varying modes of catchment area,including burial-syncline type,burial-anticline type,burial-monoclinic type and nudity-single inclined type,are introduced;and then the determination methods for catchment area in different modes are obtained.A case study is made on Jiantuowan Tunnel on Chongqing-Lichuan Railway.The catchment area of water inrush volume forecast of Jiantuowan Tunnel is regarded as burial-anticline type.As a result,the determination of the catchment area of Jiantuowan Tunnel should be paid more attentions to.
