论泾河东庄水库灰岩坝址渗漏问题

通过对泾河东庄水库灰岩坝址工程地质钻探成果特别是钻孔压水试验及水文地质成果包括区域水质、水位、水温等不连通性的分析研究,并结合流量测定三维渗漏数值模拟分析,对坝区渗漏问题进行分析和论证,进一步证明在泾河下游东庄灰岩段建坝是可行的,不会发生严重渗漏,为项目的设计、审查、决策方面参考,以促进工程前期工作的进展。

Discussion on Leakage in Calcareous Rock Dam Site of Dongzhuang Reservoir of Jinghe River

Based on the analyses on the drilling results for engineering geology specially as a water pressure test and such the test results for hydrogeology as the regional water quality, water level, water temperature and so on about the calcareous rock dam site of Dongzhuang Reservoir on Jinghe River, the leakage problem in the dam area is analyzed and demonstrated combining with three dimensional leakage numerical simulation of the charge measurement, The results further prove that it is feasible to build the dam in the calcareous rock reach in the lower course of Jinghe River and the serious leakage will not occur, so to provide some references for the design, examination and the policy-making of the project and promote the initial engineering progression,
