某水电站一断层贯穿坝基上下游，在河床上游与水库联系，且断层及下盘煌斑岩脉岩体破碎、性状差，在水库运行期长期高压水渗透作用下，可能发生逐渐软化、泥化现象，形成渗漏通道，导致坝体局部开裂。为了提高该断层的抗渗、抗变形能力等，在断层区域布置了水泥+化学浆液灌浆孔进行复合灌浆补强处理。介绍了灌浆施工技术及类似工程可以借鉴的工艺方法。

A fault penetrates the dam foundation and connects reservoir at the upstream river bed. As the broken rock and poor performance of the fault and the lamprophyre underneath, argillization and soft-ening may occur with long-term seepage of high-pressure water. This may form a seepage passage in-side the dam body and cause cracks. To improve the resistance of seepage and deformation of the fault, compound grouting using cement+chemical slurry was carried out. This paper introduced the grouting construction, for reference.
