【摘要】 岩溶地区水库渗漏问题是制约该类地区水利水电工程发展的瓶颈。如何准确的查找水库的渗漏原因是解决这一难题的关键。某岩溶地区水库在建成后经过多次修复,但坝脚渗漏量仍然达到4~5 l/s。本文以该水库渗漏原因分析和现场检测工程为依托,提出一种以"工程地质分析、水化学分析、渗漏量监测分析和探地雷达"为基本手段的分析和验证方法。该方法以水文地质控制结构定性分析为基础,通过水质分析、渗漏量监测分析确定渗水的来源,采用渗流理论分析计算排除法确定渗漏通道,进而确定水库渗漏的原因,并以探地雷达无损检测为验证辅助。该方法在现场得到了应用验证,结果表明该方法具有较好的现场适用性。更多还原

【Abstract】 Leakage of reservoir in karst area is the bottleneck that restricts the development of water conservancy and Hydropower Engineering in this kind of area. Reasons for the leakage of reservoir searching howaccurate is the key to solve this problem. A reservoir in the karst region in the completed after several repair,but the base of dam leakage still reach four or five liters per second. Detection of Engineering Basedon the leakage of the reservoir analysis and field based on. In this paper a"engineering geological analysis,chemical analysis,water leakage monitoring analysis and ground penetrating radar"as the basic meansof analysis and verification method. The hydrogeological control structure based on qualitative analysis for.Through the analysis of water quality,leakage monitoring and analysis to determine the sources of waterseepage. Analysis and calculation method to determine the leakage passage excluded by percolation theory,and then determine the cause of reservoir leakage. Taking the GPR nondestructive testing to verify the auxiliary. The method is applied in field validation,the results show that the method has applibility.更多还原
