文章对巩义市坞罗水库渗漏的情况及渗漏原因进行了分析,对各防渗方案进行了比较。根据坞罗水库的实际情况和各种防渗方案的优缺点,提出了坝体混凝土防渗墙防渗、F1断层帷幕灌浆、上游坝坡铺设膨润土防水毯、岸坡湿陷性黄土及上游坝坡裂缝采用水泥土封堵的综合防渗方案。该方案具有施工速度快、针对性强、工期短、工程投资小、防渗效果好、无需放空水库等优点,对大、中型水库的除险加固具有示范作用和应用推广价值。
The paper analyzes the seepage of Gongluo Luowu Reservoir and the cause of leakage, and compares the seepage prevention schemes. According to the actual situation of Wuluo Reservoir and the advantages and disadvantages of various seepage control schemes, the paper puts forward the seepage prevention measures of concrete seepage prevention wall of dam body, curtain grouting of F1 fault, bentonite waterproof blanket on upstream dam slope, collapsible loess slope and upstream dam Slope cracks using cement-earth integrated sealing seepage control program. The program has the advantages of fast construction speed, strong pertinency, short construction period, small project investment, good anti-seepage effect and no need of emptying reservoirs, which has the demonstration effect and application and popularization value on the reinforcement of large and medium-sized reservoirs.
