【摘要】: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。
[Abstract]:In the construction of reservoirs in complex karst areas, the analysis and evaluation of reservoir leakage is the key of Prophase investigation. In order to demonstrate the leakage conditions of the proposed Saihai Lake reservoir in strong karst area, the investigation of karst spring well, the groundwater tracer test, and the flow observation of the river reach and karst spring are adopted. Geological drilling, geophysical exploration and other methods have finally identified the karst hydrogeological conditions at the head of the proposed Sehai Lake Reservoir, and demonstrated the main karst leakage channels of the Sehai Lake Reservoir. The results show that it is not suitable to build dam and reservoir in Shai Lake area at the present stage.

【正文快照】: 塞海湖位于湖南省娄底市,该市严重缺水。因此,当地计划将塞海湖选为该城市供水水源地,初拟建一座中型水库,设计坝高30 m。但塞海湖地处强岩溶发育区,岩溶水文地质条件复杂[1-6],在此建库具有较大的风险,因此,对拟建塞海湖水库的岩溶渗漏问题进行专题研究是十分必要的。经过对,
