拔贡水电站改扩建工程溢流坝坝基基础处理

在水利水电工程中溢流坝是调节库区水位，保证水工建筑物过水安全的重要部位，其基础的安全直接关系到整个水工建筑物的安全。水体的渗流冲刷对坝基的危害是不易被发现也不易补救的，所以对坝基的基础处理显得尤为重要。文章着重介绍了拔贡水电站改扩建工程溢流坝坝基基础处理的灌浆工艺。

Foundation Treatment for Overflow Dam of Extension Project of Bagong Hydropower Station

In water conservancy and hydropower projects, overflow dam is an important part to not only the reservoir water level regulation and but also the safe water-passing of hydraulic structure, whose foundation will directly influ- ence the safety of the hydraulic structure. The harm of water seepage erosion to dam foundation is neither easily ob- served nor easily repaired, so the treatment on dam foundation becomes quite important. Therefore, the paper focuses on the grouting technology for overflow dam foundation treatment of the extension project of Bagong hydropower station.
