摘　　要：工程实际中会出现部分人工挖孔桩未挖至设计标高即遇到地下水的情况,在不进行降水的情况下,无法继续施工,此时采用高压旋喷注浆法对挖孔桩桩端地基土进行加固处理,是一种经济、快捷、安全可靠的方法。In the construction of artificial digging pile, the groundwater obstructs our steps without reaching designed depth, in the absence of dewatering, the engineering can not go on. However, another economic, quick, reliable method, high pressure jet grouting, is adopted in reinforcing digging pile foundation soil. Moreover, in the paper, the authors propose the treatment mechanism, and engineering case.
