摘　　要：针对夏季道桥路面太阳能集热过程建立简化数学模型,为集热蓄能道路融雪化冰过程仿真分析的MATLAB平台系统提供相应模块。以该模块应用为例,分别研究了道桥路面集热时介质流速、路面材质与路况等因素的影响作用。结果表明:路面太阳能集热可以获取可观的热量,并能显著降低夏季路面温度;路面料导热性能对集热能力影响基本呈线性递减关系;载热介质流速和对集热量和流体温度作用明显,从集热蓄能综合角度考虑,其中低流速时蓄能效果更加显著应优先选择。The theory of heat transfer was used to analyze the solar collection process on the slab of road and bridge in the summer, a simplified numerical model was established. It is one of program modules for computational platform of MATLAB that can simulate the running process of a road hydronic ice-snow melting （HISM） system coupled with road solar collection and seasonal underground thermal energy storage （UTES）. Using the program modules, the effect of fluid velocity, material and status of road and bridge on the characteristic of solar collection on the pavement was studied. The results show that considerable heat quantity can be obtained from solar collection on road and temperature of road surface in the summer reduces significantly. Furthermore, higher conductivity of road material has less outstanding endothermic effect, which is similar to linear decrease. At the same time, the fluid velocity has obvious influence on the hydronic temperature and heat collecting quantity. For the general, consideration of heat collection and storing energy, there is better effect of storing energy in the lower fluid velocity, which should be selected firstly.
