旧混凝土路面沥青加铺层有限元力学分析
Mechanic Performance of Asphalt Overlay on Old Concrete Pavement by Finite Element Method
【摘要】 应用A nsys软件分析了沥青加铺层路面结构在行车荷载作用下的应力状态,通过加铺层厚度、加铺层模量、混凝土模量及基础模量的改变对沥青加铺层路面结构内应力状态影响的讨论,分析了路面加铺层结构使用效果的影响因素,为路面加铺工程提供了一些建议.
【Abstract】 This paper analyzes the stress state of the asphalt overlay on the traffic load by the finite element method.And it also contrasts the stress states of the asphalt overlay when the overlay thickness,overlay modulus,concrete modulus and base modulus changes,so as to analyze the factors which influence the service performance of the overlay and provide some advice for the project of pavement overlay.
