摘　　要：以热力学理论为基础,考虑冻土相变规律,推导了冻结壁的温度控制微分方程.运用有限元方法进行模拟,分析了冻结壁的温度变化规律,得出冻结速度下各主要位置的温度状况.Based on thermodynamical considering the phase changed regulation of frozen soil, this thesis deduces the frozen soil＇s differential equation correlating with temperature. The study by the finite -element method is simulated the temperature state of some area in the highway, analyze the variational regulation of temperature for the congelatlon wall, conclude the temperature＇s distributing regulation in some main positions under certain congelation speed.
