目前,国内外对普通水泥混凝土路面的温度应力进行了深入的研究,但对旧沥青混凝土路面上加铺水泥混凝土层路面结构温度应力研究尚未开展。根据路面温度应力的计算原理,以通用有限元软件ANSYS为基础,采用三维有限元法,对旧沥青混凝土路面上加铺水泥混凝土层路面结构的温度应力进行分析,探讨了加铺层路面结构层参数对温度应力的影响规律,为寻求加铺层结构设计方法提供理论基础及依据。
At present, the temperature stress of ordinary cement concrete pavement has been studied deeply at home and abroad, but the temperature stress research on pavement structure of cement concrete pavement on old asphalt concrete pavement has not been carried out yet. According to the calculation principle of pavement temperature stress, based on the general finite element software ANSYS, the three-dimensional finite element method is used to analyze the temperature stress of pavement structure of cement concrete pavement on the old asphalt concrete pavement. The influence of parameters on temperature stress provides the theoretical foundation and basis for seeking the design method of overlay structure.
