The study show that the frozen earth in this area is mainly silty clay. The content of the dissolvable solt is relative high,which is 12.01%, and the main salinity is NaCL and KCL. The research also revealed that frozen intensity would ascend jumpily when the water contend in the soil reached its optimization( 10.61%) and kept rising,and this phenomena got more obvious with the decrease of the temperature. Between 0C and 10C, the frozen intensity vared very obviously, when the temperature is under -10C, the variety of frozen intensity got gently, and the change is not obvious. The frozen strength was influenced by the solution thickness in the soil hole.when the thickness increased, the frozen intensity decreased.
