摘　　要：在室内固结试验的基础上,通过对电镜扫描相片的分析,得到土体微结构参数(孔隙分布分维 d)及其演化规律,结合室内压缩数据对施工场地各点加固效果进行对比分析。结果表明:堆载预压法对软土地基的加固效果要好于强夯处理法。The study of this paper get a quantitative parameter-pore fraetal dimension and its developmental trend along with the pressure based on the consolidation experiment;gave a effect evaluation of the reinforcement of soft ground by dynamic compaction and the influenced area of the compaction as well as the preloading.
