摘要:
为分析沥青路面多孔混凝土基层温度应力,建立多孔混凝土基层沥青路面三维有限元模型.通过数值计算方法,分析多孔混凝土基层沥青路面的温度场,提出各自然区划内的最大温度梯度变化范围.研究了面层厚度、多孔混凝土基层厚度及模量、地基模量对温度应力的影响.对条件相同的计算结果进行了对比分析,结果表明:基层温度应力随着面层厚度的增大而减小,随着基层与地基模量比的增大而增大,随着基层厚度的增大而增大.
Abstract:
In order to analyze the temperature stress of the porous concrete base layer of asphalt pavement, a three-dimensional finite element model of asphalt pavement of porous concrete base layer was established. Through numerical calculation method, the temperature field of asphalt pavement of porous concrete base layer was analyzed, and the maximum temperature gradient variation range in each natural zone was proposed. The effects of surface thickness, thickness and modulus of porous concrete base layer and foundation modulus on temperature stress were studied. The calculation results with the same conditions are comparatively analyzed, and the results show that the temperature stress of the base layer decreases with the increase of the surface thickness, increases with the increase of the base layer to the foundation modulus ratio, and increases with the increase of the base layer thickness.
