| 中文摘要:泥岩地质条件一般较差，在这种基础上修建大型水利工程，基础处理难度较大。哈达山水利枢纽工程坝基为近水平发育的泥岩，坝基深处发育层状破碎带，严重影响坝基的稳定安全。通过分析这种地层中的涌水的渗透通道，采取了一系列注浆处理措施。这种处理方法既节约成本，又保证施工质量。结合本工程发电厂房集水井特大突水及整个P7破碎带处理方法，总结针对泥岩地层中特大涌水处理的思路和方法。 |

| Abstract:Foundation treatment is usually difficult for large water conservancy project on the mudstone which generally has poor geological conditions. The dam foundation of Hattashan hydro-junction project was constructed on flat mudstone; the stability and security of the dam foundation were seriously affected by the deep layered fracture zone. Analysis on the outgush infiltration channel was made and a series of grouting method were taken. This approach not only saves cost, but also ensures the construction quality. The article summed up the treatment method of special gushing water in the mudstone on the basis of the large water inrush in powerhouse water collecting well and in the P7 fracture zone; it is worth to be the reference. |
