Numerical simulation of frost heave in frozen soil under various freezing mode

摘要

In this paper frost heave is simulated numerically by the coupled processes of heat conduction and moisture transport within frozen soil mass. A finite difference computational program developed by the first author is used to simulate frost heave of one-dimensional frozen soil under three different freezing modes including continuous, stepwise and continuous-intermissive mode. The results of simulation show that continuous-intermissive mode can suppress the magnitude of frost heave effectively.
