摘要
基于低温期的气候特点,采用有限元软件ABAQUS对本文对半刚性沥青路面结构温度场进行了模拟,分析了不同时刻路面内部温度随外界环境的变化规律,进一步的研究了在周期性气候作用下的路面结构内部温度应力,为低温期沥青路面结构设计提供理论依据。
In this paper,temperature field was simulated by ABAQUS software based on low temperature and the change law of pavement structure temperature under different moment was analyzed. The temperature stress under climatic periodic variation was further studied. That can be provided theoretical foundation for design of asphalt pavement structure.
