龙潭河水库右岸岩溶渗漏问题分析

Analysis of Leakage Problem of Right Bank of Longtanhe Reservoir

龙潭河水库位于强岩溶区,在地质勘察过程中发现水库右岸河间地块可能存在岩溶渗漏问题,成为影响水库能否成库的制约因素。为查明右岸河间地块是否存在地下水分水岭及其与水库正常蓄水位的相对关系,在掌握水库基本地质条件的前提下,有针对性地采取泉井调查、地下水示踪试验、地质钻探、钻孔地下水位长期观测等综合勘察手段,对水库岩溶渗漏问题进行了全面深入分析,尤其对水库右岸地下水位获取及可靠性进行了探讨,最终得出在拟定的正常蓄水位时,水库不存在岩溶渗漏问题的结论。

The Longtanhe reservoir, located in the karst area, is found that there exists karst leakage problems on the right bank. To find out the geological conditions of right bank and the leakage possibility, the well investigation, groundwater tracer testing, geological drilling, long-term observations of ground water level, have been carried on. It is concluded that with the normal storage level, the reservoir has not the karst leakage problems.
