    温度对季节性冻土水分迁移的影响研究

    TEMPERATURE ON THE SEASONAL MIGRATION OF FROZEN WATER

    • 摘要: 寒区季节性冻土冻胀性质对工程实际影响很大。为了了解温度对水分迁移现象的影响,本文通过地温测试仪对野外不同深度处的土层温度进行测量,并在不同时间相应深度取土样,测其含水率,通过比较不同时间不同深度处的含水率的变化情况来分析温度变化对水分迁移现象的影响。在气温回升之前,当地表温度降低时,温度随深度的降低而升高; 随着地表温度不断降低,各深度处的温度也不断下降,温度梯度增加,各深度处地层的含水率变化大,即温度梯度的增加促进了季节性冻土区水分迁移现象的发生。

       

      Abstract: 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.
