摘　　要：利用读数显微镜位移跟踪法,对黄土进行了强夯的模型试验研究,分析了不同的参数对强夯加固范围的影响程度和相互关系,得出了考虑这些主要因素的加固深度的计算公式,并对强夯机理进行了分析。A series of experiments of dynamic compaction of loess were carried out with different parameters by displacement tracing method with microscope. Based on the results of model testing, the relationship between the satisfactory improvement depth and the main factors was analyzed, and a formula of satisfactory improvement depth including more factors was obtained. The mechanism of dynamic compaction was described. The experimental results can be used for highway engineering.
