摘　　要：介绍了斜孔压力灌浆加固软弱地基的一个成功实例．对于具有整体筏板基础的已建房屋，在其周围打斜孔，压力灌浆加固基础下的软弱地基，不失为一切实可行的最佳途径，但其理论和方法还不够完善和成熟，本文结合工程实例，阐述该方法的理论分析和方案设计思路，以供工程设计和施工人员参考．This paper introduces a successful engineering example of reinforcing soft foundations through raking aperture pressure grouting.The way is unquestionably realistic for the reinforcement of the completed building with a whole raft foundation.But the way remains to be perfected and developed both in tems of theory and in manipulation.Based on the engineering example,the paper analyzes the way theoretically and provides the schematic design thought for the engineering designer and builder to refer to.
