摘要: 地下水垂向循环水动力条件是岩溶发育深度的主要控制因素。为探求川东背斜构造岩溶区多级水流系统控制下的岩溶强发育深度，采用地理信息系统（GIS）技术，选取地形指数和水动力坡降构建岩溶水动力强弱的量化因子FHQ，并结合钻孔数据推求假角山背斜构造区地下岩溶强发育深度。研究显示：水动力因子FHQ与地形指数、水动力坡降在空间上呈明显正相关关系，同时可指示岩溶水流系统向深循环的深度，以此推求背斜构造区地下岩溶的强发育深度下限。假角山背斜两翼FHQ集中在0.1~0.4之间，岩溶水动力整体偏弱，深沟FHQ值整体高于浅沟。东、西翼深沟控制下的地下岩溶强发育深度分别约40~100 m和110~180 m；浅沟控制下的地下岩溶强发育深度分别约15~60 m和10~90 m。研究成果可进一步丰富川东背斜区岩溶发育评价方法体系，为隧道工程岩溶突水灾害预测防治提供理论依据。Abstract: The hydrodynamic condition of groundwater vertical circulation is the main factor to control the development depth of karst.In order to explore the karst strong development depth under the multistage flow system in the anticline karst area of East Sichuan.The quantitative factor of karst hydrodynamic strength(FHQ) is constructed by using GIS technology and selecting topographic index and hydrodynamic gradient.Combined with drilling data, the depth of strong development of underground karst in Jiajiao Mountain anticline structure area is calculated.The results show that the hydrodynamic factor FHQ is positively correlated with topographic index and hydrodynamic gradient in space.At the same time, it can indicate the depth of deep circulation of karst water flow system, so as to calculate the lower limit of strong development depth of underground karst in anticline structural areas.The FHQ of the two wings of the Jiajiao Mountain anticline is between 0.1 and 0.4, the karst hydrodynamic force is generally weak, and the FHQ value of the deep ditch is generally higher than that of the shallow ditch.The strong development depth of underground karst under the control of deep trenches in the east and west wings of anticline is about 40-100 m and 110-180 m respectively.It is hoped that the research results will further enrich the evaluation method system of karst development in east Sichuan anticline area.It also provides a theoretical basis for the prediction and prevention of karst water inrush disaster in tunnel engineering.
