摘　　要：在模型试验的基础上，对高含水量的粘土隧道冻结的地表变形及深部地层的位移进行了研究，得出了隧道冻结位移随温度变化的特性及其分布特点．On the basis of model test, this paper does some research on the surface and deep displacement of the high water clay when artificial freezing method is being used as an aided method in the tunnel construction. After research, the specific property of displacement changing with the temperature and its distribution characteristics is obtained.
