| 摘 要： | 通过利用液氮制样技术制备饱和软土试样，借助扫描电子显微镜技术，本文对广东科学中心强夯试验区进行了软土微结构特性定量分析。通过比较试样的孔隙度、孔隙总面积、孔隙总个数、平均孔隙周长、孔隙平均直径及孔洞的复杂度，初步探讨了动力排水固结技术对饱和软土地基处理的影响。

| Abstract: | Based on the sample-made technology of the liquid nitrogen, 46 group samples of saturation soft soil have prepared. With the help of scan electron microscope (SEM) technology to microstructure, the quantitative micro-structure characteristic analysis on them for the dynamic consolidation trial zone in Guangdong Scientific Center has been made. Having compared the results in terms of the porosity, the total area of poles, the number of holes, the average circle of holes, the average area of holes, the complicated degree of holes, and the average diameter of holes, the efficiency of dynamic consolidation mothod to saturation soft soil treatment has been discussed. |
