汪家口水库除险加固库盘渗漏分析与研究

Study on eliminated danger and reinforcement about prevent leakage of reservoir plate of Wangjiakou reservoir

汪家口水库位于开垦河冲洪积扇中下部,引开垦河水入库,是一座注入式丘陵水库。建于1992年,当时水库库盘采用防渗膜防渗,经过几年的运行发现渗漏比较严重,造成库水利用率较低。2006年8月对该水库进行了除险加固,但由于多种原因,导致处理不彻底。采用中法勘探探测渗漏点,结果与传统勘测基本吻合。通过对汪家口水库库盘渗漏的分析与研究,提出水库除险加固中应予以重视的一些问题。

Wangjiakou reservoir is an injection style hill-reservoir,located at the lower part of alluvial fan of Kaiken river,Storaged the Kaiken fiver. Wangjiakou reservoir is built in 1992,reservoir plate was adopt anti-impermeable membrane to prevent leakage ,＇after several years of operation was found that infiltration was heavy, which caused lower utilization rate of water.The reservoir is eliminated danger and reinforcement in August 2006. This article is in the process of eliminating danger and reinforcement,through investigate the reservoir plate leakage status,studied and analysised the disose program,finally,the reasonable and optimal solution to the reservoir leakage has been put forward.
