摘　　要：为了解决宁夏固原市某工程地基的黄土自重湿陷性问题,采用人工挖孔灌注桩对地基土进行了处理,同时进行了相关理论计算分析.结果表明,人工挖孔灌注桩可以有效消除黄土湿陷性,工程应用前景广阔.In order to solve the problem of the loess collapsibility weight of Guyuan in Ningxia. This work gives a practical engineering case by using artificial cast-in-place piles to improve foundation soil, and related theoretical calculation is given. The result shows that artificial cast-in-place piles can help to eliminate the loess collapsibility effectively. This application has broad prospects, and is worth popularizing and application.
