摘　　要：通过某工程的设计实践,针对高填方湿陷性黄土地基的处理方案进行对比。一种为灰土桩和CFG桩的二元桩复合地基,另一种为钢筋混凝土灌注桩后注浆布桩,通过对两种处理方案进行了详尽比较,最终确定采用钢筋混凝土灌注桩后注浆的地基处理方案。该方案既简化了施工程序加快了施工进度保证了施工质量,又取得了较好的经济效益。并且在同类型的地质条件下,此方案具有一定的参考价值。In the article, the treatment scheme of collapsible loess foundation with high fill is compared through a practical engineering. O n e for the lime-soil pile and CFG pile binary pile composite foundation, the other for the concrete filling bearing platform. The two methods were c o m-pared in detail, and finally determine the use of concrete grouting pile grouting after foundation treatment program. This method not only simpli-fies the construction process to speed up the construction progress to ensure the construction quality, but also achieved good economic benefits. And this program has a certain reference value in the same type of geological conditions.
