摘要
根据西安地区的气象资料和路面温度的热物理参数,应用传热学的有关理论和假设边界条件,应用ANSYS工程分析软件模拟求解路面温度场,并以此作为温度应力数值计算的温度物理环境,进行了半刚性基层沥青路面结构的应力分析。分析结果表明,路面表面温度同基层顶面最高最低温度的出现存在时间差,同时路面温度应力随时间的变化只发生在路面结构一定深度范围内。
Based on the climate data and thermal physical parameters of the road temperature in Xi＇an, diathermanous theory and hypothetical border conditions are applied and at the same time, ANSYS engineering software is used to explain in a simulative way the temperature field of the road surface, which is used as the temperature physical environment of temperature press numerical value calculation and press analysis of thesemi-rigidity skeleton asphaltum road surface structure is made. Analysis results show that time difference exists in the appearance of road surface temperature and skeleton top highest and lowest temperature; that theknowable road surface temperature press changes with time happens only in the road structure with certain depth.
