重载交通下水泥砼路面力学机理的影响分析

以水泥砼路面结构与重载交通特性为研究实体，结合南方省份高温的区域性特点，轴载偏重，轴载次数多，接地压强大，采用三维有限元程序对最不利荷载位置的水泥砼路面的动力特性进行了模拟，得到板厚、基层厚度与模量、地基刚度、接缝等重要参数对水泥砼路面结构力学行为的变化规律，为水泥混凝土路面结构设计、路面结构在重载作用下的力学响应提供了理论依据和参考。

Analysis on the influence of the cement concrete pavement mechanics mechanism under heavy transportation

In this paper,combined with the regional characteristic of south province high temperature including heavy axial load,axial load number of times,big gravity of freight train were represented as research bodies.The dynamic characteristic of the cement concrete pavement in the most disadvantageous load location was simulated by using three dimensional finite element methods.The variation of the cement concrete pavement structural mechanics behavior with the important parameter of board thickness,base thickness,base module,foundation stiffness and joints were obtained.The results provided the theory basis and the reference for the design of the cement concrete pavement and the mechanical response of pavement structure under the heavy transportion.
