Abstract：Research purposes: Karst is the most serious unfavorable geology problems about the railway project m the southern karst area, therefore the research of the engineering geological conditions become the main content of geological survey work. This article takes Dabaoliang tunnel in Qianjiang-Zhangjiajie-Changde Railway as an example，analyzes and researches the karst development regularities and control factors by the comprehensive survey methods，and provide a reference for karst region geological survey in the future.
Research conclusions: This article get the following conclusions according to the research and analysis of karst development regularities and control factors of Dabaoliang tunnel:(1)Confirming the position of four more large-scale karst conduit and fracture flow system in the area，which provide the reference for tunnel design work;(2)It should adopt the comprehensive engineering geological exploration methods，combining the interpretation of aerial photoes， ground survey，hole survey，geophysical exploration and other methods，to further reveal the karst development regularities and achieve investigation purpose;(3)This article provide the certain reference value for the future geological survey in karst area.
