摘　　要：龙虎水库自建成后渗漏量大,后经2次补强灌浆,效果仍然不理想。此次大坝除险加固采用左岸灌浆+右岸坝体、坝基混凝土防渗墙+右坝肩延长线灌浆的分部位不同防渗体系组合方案。防渗墙最大深度达91.5m,渗漏严重的基岩段也采用防渗墙防渗,入岩最大深度达82.2m,采用塑性混凝土和普通混凝土相结合。通过该工程的成功实施,积累了设计、施工、检测等方面的经验。Longhu Reservoir has experienced significant leakage since its construction,and despite two rounds of reinforcement grouting,the results are still unsatisfactory.This dam reinforcement adopts a combination of different anti-seepage systems,including left bank grouting,right bank dam body and foundation concrete anti-seepage wall,and right dam shoulder extension line grouting.The maximum depth of the anti-seepage wall is 91.5m,and anti-seepage walls are also used for severely leaking bedrock sections.The maximum depth into the rock is 82.2m,and a combination of plastic concrete and ordinary concrete is used.Through the successful implementation of this project,experience has been accumulated in design,construction,testing,and other aspects.
