摘要
水泥混凝土路面缩缝宽度的变化将导致路面板块之间荷载传递状况的改变,进而影响路面板的荷载应力状态。利用三维有限元计算程序EverFE分析缩缝宽度与路面板荷载应力的关系,指出减少缩缝宽度变化的影响,对延长水泥混凝土路面的使用年限具有重要作用。
The variety of cement concrete pavement contraction joint width affects the load transfer be- tween pavement panels, as well as the load stress state of pavement panels. In this paper, the authors utilized 3D finite - element computational prograrn EverFE to analyze the relationship between contraction joint width and load stress of pavement panels. The results indicate that reducing the influence of contraction width variety would have important effect on prolonging service life of cement concrete pavement.
