TEMPERATURE ON THE SEASONAL MIGRATION OF FROZEN WATER

Cold nature of seasonal frozen soil engineering has great influence of temperature on moisture migration in order to understand the impact of the phenomenon,this paper tester temperature at different depths of field measurements of soil temperature and depth at different times to take the appropriate soil samples,measuring the water content. By comparing the different times the moisture content at different depths to analyze the changes in temperature on the moisture migration phenomenon. Rise in temperature before the local surface temperature is lowered,temperature the decrease with depth De increased; of the soil temperature is lower,the depth of the temperature Ye Department declining temperature gradient increased,the depth of the water formation rate changes Offices big,that the increase of the temperature gradient for the seasonal frozen soil moisture migration phenomenon.
