卡加水库渗漏分析及处理措施研究

摘要

Reservoir leakage has serious impact on water resources .The authors correctly analyze the cause of reservoir ’s leakage ,so that they can take effective control measures .Based on the Kajia Reservoir as an example ,through geological survey on field ,they preliminary judge that the reservoir ’s leakage is on the right of dam ,and further from aspects of com-prehensive analysis of water quality analysis ,rock mass permeability ,quantity of seepage water and reservoir water level , quantity of seepage water ,point out that the dam abutment leakage ,the seepage around the dam and valley leakage are the direct causes of dam leakage ,leakage of dam abutment is the most main reason for the leakage of reservoir .They put forward relevant measures for seepage control in order to offer a reference for the similar projects .%水库渗漏严重影响水利资源的利用，正确分析水库渗漏的原因是采取有效的治理措施的基础。以卡加水库为例，通过现场地质调查，初步判定为右坝脚存在渗漏问题，并进一步从水质分析、岩土体透水性、渗水水量与库水位关系、渗水水量等多方面综合分析，指出坝肩渗漏、绕坝渗漏、邻谷渗漏是水库渗漏的直接原因，其中坝肩渗漏是水库渗漏的最主要原因，并提出相关防渗处理措施。
