岩溶水动力类型的勘察和分析方法的探索与实践

Exploration and practice of investigation and analysis methods for karst hydrodynamic types

隨着高速度公路、铁路、引调水水利工程建设的推进,越来越多的工程穿越岩溶发育区域是不可避免的,建设过程中通过岩溶水动力类型的研究,探索采用合理的、符合实际的、可行的勘察手段和分析方法,可以查明岩溶水文地质结构、河谷水动力条件、河谷水动力特征、河水与地下水补排关系,以及岩溶水动力的基本类型、岩溶地下水循环带的水动力类型、岩溶的发育基本规律和发育深度,可以解决工程的渗漏问题和岩溶环境工程地质问题,起到事倍功半的效果,对保护岩溶地下水资源具有现实意义。

With the advancement of high-speed highway,railway,water diversion and water conservancy projects,it is inevitable that more and more projects will pass through the karst development area.During the construction process,through the research of karst hydrodynamic types and the exploration of reasonable,practical and feasible investigation method and analysis method,the karst hydrogeological structure and river valley hydrodynamic conditions can be identified.The hydrodynamic characteristics of river valley,the relationship between river water and groundwater recharge and discharge,the basic types of karst hydrodynamic forces,the hydrodynamic types of karst groundwater circulation zones,and the basic laws and depths of karst development can solve the seepage problems and the engineering geological problems of karst environment,and play a two-for-one effect on the engineering,and have practical significance for the protection of karst groundwater resources.
