| 摘 要： | 在研究越冬期土壤的水热耦合运移规律时，通常需要同步测定土壤冻结深度，为了分析冻融期土壤剖面的冻结情况，我们在室内对3种土质的土壤进行了土壤冰点测试实验，测定了土壤冻结的时间过程及不同含水率、含盐量条件下的3种土质的冻结温度(冰点)。分析了土壤冻结温度随土壤含水量及含盐量的变化规律，为确定试验区越冬期土壤冻融状况提供了依据。

| Abstract: | When we study the infiltration characteristics of frozen soil during winter and spring, the soil frozen depth were usually required to be measured simultaneously.For the sake of analyzing the frozen state of the soil section, measurement experiments of soil frozen temperature of three kinds of soil were conducted. Freezing process and freezing point under different water contents and different salinity were determined. The variety regulations of soil frozen temperatures with water contents and salinity were analyzed, which would provide basis for determining soil freezing and thawing in the winter and spring in the experiment area. |
