摘　　要：珠江三角洲广为分布的高含水量软土的地基处理问题是工程实践中迫切需要解决的难题．其关键问题有三：①地基处理措施的选择基本处于经验直觉阶段；②地基处理方案的设计缺乏科学依据；③工后沉降的预测急需给出可行的方法．在现场施工中也有人进行过对比探索，西安公路交...The main problems in the improvement of soft foundations are to give the scientific basis to the design and to find a practicable way to predict the settlement after finishing the project. From the authors viewpoint, all problems focus on one point: the complicate microstructure.No matter what measures you take, the aim is to improve the microstructure of soft clay. In the paper, the author points out some new thinking about the control of soil improvement by microstructure, and gives the optimum design and the test way of the effect of sand well. Finally, the author presents a new way to predict the ground settlement after finishing the project.
