摘要
在同一水文地质单元内,两股水流交叉流动,但互不干扰或归并,这是岩溶水文地质的一个特殊现象。它包括两种类型:一种是地下水之间的穿跨流,另一种是地下水与地表水之间的穿跨流。穿跨流是岩溶发育过程一定阶段的产物,是岩溶水排泄基面演化的结果。地下水对地表水的穿跨,与该地段地表水的悬托性质有关。对穿跨流的研究有助于对一些岩溶水文地质问题深入地分析和认识,诸如:对岩溶区地下迳流汇水范围的考虑;对岩溶水库渗漏的讨论;以及对岩溶演化及岩溶水文地质的某些理论概念的研究等。
Two groundwater flows intercrossing each other in the same hydrog-eological unit, neither disturbing nor merging into each other, is a special phenomenon of karst hydrogeology. It includes two types: intercrossing between different groundwater flows, and intercrossing between groundwater flow and surface water.
The intercrossing of different water flows is the result of evolution of base level of karst water drainage in a particular stage of karsti-fication process. In case of groundwater flow crossing surface water, it has something to do with the perching character of surface water.
Study of intercrossing flows is conducive to in-depth analysis and understanding of some particular karst hydrogeological problems, such as: catchment area of underground water flow in karst region; assessment of leakage of reservoir in karst region; and approach to some theoretic concepts on evolution of karstification and karst hydrogeology, etc.
