Application of ABAQUS in Lean Concrete Base Asphalt Pavement

主要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.介绍了贫混凝土基层沥青路面温度应力的计算原理,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 text mainly introduced the application of the common finite element software ABAQUS in lean concrete base asphalt pavement. Introducing the calculation principles of temperature stress of lean concrete base asphalt pavement, On the basis of the software of finite element method（ABAQUS）, 3-D FEM is used to analyze temperature stress for Open -graded Large Stone Asphalt Mixes （OLSM） of asphalt pavement, It discusses the influence rule of pavement design parameters for temperature stress,and offers the theoretical basis for structural design of OLSM.
