摘　　要：冻胀是冻土材料的一种最为显著特性,冻胀引起土体位移将对周围环境产生危害。通过自行研制的微机控制多功能冻土冻胀试验机对典型粘土进行了四因素三水平正交试验,从试验结果中分析出各因素对土体冻胀率的影响程度的主次顺序。The heave will be the frozen earth material one kind of mostremarkable characteristic, the heave causes the soil body displacement to have the harm to the environment, when the frozen earth heave will receive the hindrance, will have the very big action to the structure, possibly will cause the structure destruction. This article through the microcomputer which independently developed controls the multi-purpose frozen earth heave testing machine to carry on four factors three levels orthogonal experiments to the model clay, analyzed various factors from the test result to the soil body heave rate influence primary and secondary order.
