摘要
使用有限元软件建立了更加符合实际的高温天气下连续配筋混凝土加铺沥青层复合路面温度应力分析模型,综合考虑路面各结构层厚度方向的温度梯度非线性分布和温度周期性变化,以1 d为周期计算了混凝土层的温度应力,并总结了非线性温度梯度、沥青层厚度、CRC层厚度和基层摩阻系数对混凝土温度应力的影响规律。
The temperature stress analysis model of continuous reinforced concrete overlaid asphalt cursecomposite pavement more in line with the actual high temperature weather is established by the finite element software. This paper comprehensively considers the temperature gradient nonlinear distribution and temperature periodical change in the thickness direction of pavement structural layers. This paper calculates the temperature stress of concrete layer by the period of 1 d, and summarizes the influence laws of nonlinear temperature gradient, asphalt layer thickness, CRC layer thickness and base friction coefficient on the concrete temperature stress.
