摘　　要：喀斯特区水文地质条件普遍较复杂,而线性工程又具有路线狭长、跨地质单元多、地质条件变化大等特点,水文地质勘察难度随之增加。文章通过资料收集、工程地质调绘、钻探和物探相结合的综合水文地质勘察方法,从喀斯特发育程度、空间分布特征等角度分析了场区喀斯特发育特征,查明了场区分水岭及侵蚀基准面分布情况,并以此沿路线走向划分了多个水文地质单元,分区分析地下水补给、径流、排泄及动态变化等水文地质条件。The hydrogeological conditions in karst area are generally complex.The linear engineering has the characteristics of long and narrow route,many crossgeological units and large changes in geological conditions,and the difficulty of hydrogeological investigation increases.In this paper,through the comprehensive hydrogeological survey method combining data collection,engineering geological mapping,drilling and geophysical prospecting,the karst development characteristics of the field area are analyzed from the perspectives of karst development degree and spatial distribution characteristics,and the distribution of watershed and erosion base level in the field area is found out.Then,several hydrogeological units are divided along the route,and the hydrogeological conditions such as groundwater recharge,runoff,discharge and dynamic change are analyzed.
