摘　　要：针对太阳能-土壤源热能复合道路融雪系统融雪过程,基于自行开发的道路融雪系统融雪模型,采用仿真分析的方法探讨环境温度、雪层厚度、输入热功率等融雪条件对融雪过程中的待融阶段、融化阶段及融后蒸发阶段融雪特性的影响;在此基础上,基于显著影响不同阶段融雪特性的因素,开展太阳能-土壤源热能复合道路融雪系统运行策略的研究,建立针对融雪过程不同阶段的系统运行过程控制图,提出融雪系统运行策略,为太阳能-土壤源热能复合道路融雪系统的运行过程控制提供参考。A two-dimensional heat and mass coupled model for the snow-melting process was presented using solar- ground source coupled snow-melting system for pavement firstly. By means of this model, the effect of the factors, such as ambient air temperature, equivalent snowfall depth, input heat flux on snow-melting characteristic in snow melting process was investigated. Based on the above results, process control charts for different snow inching period were developed. And operation strategy for solar-ground source coupled snow-melting system for pavement was suggested. The proposed method will give a lot of suggestion in the operation of solar-ground source coupled snow-melting system for pavement.
