| 摘 要： | 泥化软化性F_5断层是故县大坝坝基范围内最大的一条断层,位于左岸,对左坝肩的稳定极为不利,采用水泥灌浆处理无效,故改用化学灌浆处理。选用EAA化学浆材,采用“优选组合配方综合施灌”的创新施工工艺,效果良好,为今后低渗透性复杂的泥化软化性断层的防渗加固处理,提供了新的依据和途径。

| Abstract: | The argillaceous and softening F5 fault is the largest fault in the Guxian darn foundation. It streches in the left bank and is harmful to the stability to the left abutment. Cement grounting is of no use to it, so chemical injection is adopted. EAA chemical grounting material, and a new construction technology are adopted with good results. This construction technology has provided new basis and methods for seepage prevention stabilization of complicated argillaceous and softening faults with low permeability. |
