摘要
建立了有大气温度突变情况下的土壤温度场的数学模型,推导出受气温突变影响的土壤温度场解析解,分析了气温突变时各种因素对土壤温度场的影响程度,并与实测数据进行了对比分析,验证了模型及求解方法。
Soil temperature field is the primary factor that affect the design, operation and management of various underground projects. The mathematical model of soil temperature field under the abrupt changes of air temperature was established, and the analytic solution for soil temperature field was dedused. The effects of varieties factors on the soil temperature field during the abrupt changes of air temperature were analyzed. The testing data were analyzed and contrasted with the calculation result, and the validity of the model and the solving method were verified.
