ABAQUS在贫混凝土基层沥青路面结构计算中的应用

Application of ABAQUS in Lean Concrete Base Asphalt Pavement

介绍了有限元通用软件ABAQUS在贫混凝土基层沥青路面中的应用问题。在介绍贫混凝土基层沥青路面温度应力计算原理的基础上，以通用有限元软件ABAQUS为基础，采用三维有限元法，对开级配大粒径沥青碎石缓解层沥青路面的温度应力进行分析，探讨了路面结构层参数对温度应力的影响规律，为寻求开级配大粒径沥青碎石缓解层沥青路面的结构设计方法提供理论基础及依据。

This paper mainly introduces the application of the software ABAQUS in lean concrete base asphalt pavement. On the basis of the software ABAQUS, the temperature stress of lean concrete base asphalt pavement is introduced, and temperature stress for open - graded large stone asphalt mixes（OLSM） of asphalt pavement is ana- lysed by 3 - D FEM , finally the influenc of pavement layer parameters on temperature stress is discussed , which provides theoretical foundation for structural design of OLSM
