塞海湖水库库首岩溶渗漏问题研究

在复杂岩溶区修建水库,对水库渗漏问题进行分析评价是前期勘察的关键,往往需要采用多种方法进行综合分析研究。为论证强岩溶区拟建塞海湖水库的渗漏条件,采取岩溶泉井调查、地下水示踪试验、河段及岩溶泉流量观测、地质钻探、物探等多种方法,最终查明了拟建塞海湖水库库首的岩溶水文地质条件,论证了塞海湖水库的主要岩溶渗漏通道,结果表明现阶段塞海湖地区不宜建坝成库。

Research on karst leakage problem in Saihaihu Reservoir head

When reservoir is constructed in complex karst area, the key point in preliminary investigation is to analyze seepage problems and often a variety of methods are required for comprehensive analysis and research. We took several methods including karst spring and well survey, tracer test of groundwater, flow observation of river and karst springs, geological drilling，geophysical prospecting and so on to demonstrate seepage conditions of the proposed Saihaihu Reservoir, a barrier lake in strong karst area, and finally made the karst hydrogeological conditions clear and found out the main karst seepage passage of Saihaihu Reservoir head. The result shows that it is not suitable to construct reservoir at Saihaihu at this stage.
