摘　　要：加固深度、夯沉量等是评价强夯法处理黄土湿陷性的主要指标,而影响处理效果的因素主要有黄土的含水量、孔隙比以及强夯夯击能量。通过对大量中低能量强夯法处理湿陷性黄土的工程实测数据的分析,得到适宜强夯处理的黄土含水量范围,而后用多元线性回归法建立强夯处理深度与夯沉量与相关因素的关系。Effective reinforced depth and settlement of dynamic compaction are the two major indexes in evaluation of effect of dynamic compaction in collapsible loess,and the main factors influencing the treatment effects are water content,void ratio of soil and tamping energy.By analysis of large amount of data on projects treated by low-middle elnrgy dynamic compaction in loess,the water content conditions for dynamic compaction were obtained,and the relationship between treatment effects and influencing factors was established by multivariate linear regression analysis.
