水分迁移与管道埋深对土壤温度场的影响

Influence of Buried Depth of Pipeline and Moisture Migration on Soil Temperature Field in Permafrost Regions

管道埋深和土壤中的水分迁移对于冻土区埋地管道土壤温度场的研究有着重要的影响,研究水分迁移和管道埋深对温度场的影响,利用数值模拟的方法进行计算,并对计算结果进行了分析,结果表明,在冻土区,埋深越大,周围土壤的温度越高;土壤含水量越大,土壤的温度越高;同时对比不同含水量和不同埋深对温度场的影响可得埋深越小,不同含水量之间的土壤温度差就越大。

Buried depth of pipeline and moisture migration in the soil have important effect on the research of soil temperature field around the pipe in permafrost regions. In this paper, influence on the moisture migration and buried depth of pipeline on soil temperature field was investigated by using the method of numerical simulation, and the calculation results were analyzed. The results show that, in permafrost regions, the larger the buried depth, the higher the soil temperature; the higher the moisture content, the higher the soil temperature; at the same time, the smaller the buried depth, the higher the temperature difference of soil with different moisture content.
