摘　　要：根据工程的地质情况,结合工程实例,不仅介绍了采用DDC桩消除地基湿陷性,还介绍了桩侧桩端后压浆技术的加固机理和施工工艺,以及注浆效果及其对单桩承载力和沉降的影响。试验检测结果表明该方案能够满足设计要求,证明了本工程所采用的地基基础方案的应用是成功的。以便为其它工程的实际应用提供一些参考。In this paper, according to the engineering geological conditions, combined with the engineering practice, not only presents the pile foundation DDC eliminate the collapsible sex, it presents the reinforcement mechanism and construction process of the pile-side and pile-end post grouting technique, as well as the influence of the grouting effect on the single pile bearing capacity and settlement. The test results showed that the system can satisfy the design requirement, prove that the application of the foundation scheme in this project is successful. Through the presentation of this paper,so as to provide some references to the actual application of the other project.
