Seasonal Soil Freezing Characters in Daxinganling

Abstract:

For understanding the transport of groundwater existing in the seasonal freezing soil，laboratory test and field monitoring (frozen depth、moisture content and ground temperature in five months) were carried out in Daxinganling. A translocation model is built to analyze water behavior. The result shows that thermal conductivity will increase approximately one percent when temperature decreases 1°C. A transition function is used to prevent non-convergence in the numerical simulation. The simulation proves that the modified numerical simulation can reveal the law of moisture and heat translocation, and further offer guidance in practice.
