主　　题：Saturated soil Frozen heave Rigid ice model Simulation 

摘      要：The relation between ice pressure and load as a criterion of segregated ice initiation is introduced into the rigid ice model to simulate frost heave in saturated and granular soil. The calculated results show that unfrozen water content, thermal conductivity and hydraulic conductivity change greatly in frozen fringe. In numerical simulations, the influence of load, hydraulic conductivity and property of soil containing water on the process of soil freezing are analyzed, and the simulation curves such as cumulative heave, the change of depth of frozen and the distributions of water content are similar to the observations reported elsewhere.
