摘要
夹河子水库大坝座落在第四纪砂砾石、细砂层强透水地基上。由于多年未采取有效的防渗措施，坝体与坝基接触面存在严重的冲刷破坏，形成了空洞，渗漏严重。坝体内存在有流塑态土体和粉细砂夹层，且已形成了渗漏通道。针对这种情况，采取了以充填灌浆与高压喷射灌浆相结合，构筑全截式防渗板墙的处理方法，取得了较好的效果，证明对强透水砂砾石地层采用高喷截断式灌浆处理是可行的。
Jiahezi Reservoir Dam lies on strongly water infiltrating bed being composed of grit gravel and arentilla formed in the Fourth Period.Because of taking no effective measurse to control seepage for many years,contact face between dam body and dam base is damaged badly,causing cavity and serious seepage loss.The existing flow plasticitg and arentilla in the earth dam block have formed seepage paths.In view of the situation mentioned,the ways of combination of filling grouting with jetting grouting at high pressure ,and building whole-retain seep proof screen have been used,which have shown good effect and proved to be practical.
