用沥青砼罩面的碾压砼路面板温度应力分析

Temperature Stress Analysis of Roller Compacted Concrete Pavement with Asphalt Concrete Overlay

根据用沥青混凝土罩面的碾压混凝土复合式路面结构温度场分析结果，用三维有限元法分析用沥青砼罩面的碾压混凝土路面板温度应力．探讨沥青混凝土罩面层厚度、碾压混凝土线胀缩系数、板长和板厚对温度应力的影响．文中最后给出了用沥青混凝土罩面的碾压混凝土板温度翘曲应力系数。

Based on the analysis results of temperature field in the roller compacted concrete pavement with asphalt concrete overlay,the temperature stresses in the RCCP with asphalt concrete overlay by three dimension finite element method is analyzed. It is discussed that linear expansion coefficient of RCCP plate length and thickness has an influence on temperature stress. The warping stress coefficient of RCCP with asphalt concrete overlay is given.
