一种新型混凝土路面的有限元分析

FEM Analysis of a New Cement Concrete Pavement

根据弹性半无限地基上弹性薄板力学模型理论,结合三维有限元法,采用典型的水泥混凝土路面结构,利用大型通用有限元分析软件AN SY S的接触非线性模块,对一种新型的企口板路面进行了模拟仿真,并计算分析了几种材料参数对路面力学性能的影响,企口板接缝之间的传荷能力,为今后的水泥混凝土路面结构分析提供参考.

Based on the theory of elastic-thin-slab mechanics model on elastic semi-infinite subgrade and the three-dimensional finite element method,a typical cement concrete pavement was put forward.The FEM model of a new matchboard cement concrete pavement was built with the contact non-linear module of ANSYS.The mechanical responses of the cement concrete pavement to several material parameters and the different vehicle loads as well as the load transfer ability of the matchboard joints were analyzed.The results provide a reference for further study of cement concrete pavement structures.
