摘　　要：采用室内实验对邯郸击实膨胀土的膨胀变形进行测试,根据试验结果对击实膨胀土变形规律及膨胀变形速率进行了定性分析,分析得出膨胀率与初始含水率、初始干密度、竖向压力相关关系,并给出了膨胀率与它们的综合定量关系。In this paper,indoor test is used to analyze the expansion and deformation of the expansive soil in Handan. According test result,the qualitative analysis about the fatten and speed of expansion is put forward. It analyzes the relation about the expansion and primitive water content, primitive dry density and vertical press. The quantitative analysis is also given about their cornp relationship.
