摘　　要：本文采用数值分析方法,分析了水泥路面板内荷载应力与板块尺寸关系,探讨了企口缝尺寸对板内拉应力、剪应力分布以及接缝处弯沉传递效果的影响。结果表明:板块尺寸对板内X、Y向最大拉应力值影响显著,同方向最大拉应力可达最小值的3.5~5倍;不同尺寸企口缝的路面板传荷能力差异明显,并提出相关优化方案。Numerical analysis was adopted to analyze the relationship between pavement slab internal stress and sizes and explore the influence of the sizes of tongue-and-groove joint on pavement slab internal tensile stress and shear stress distribution and deflection transfer effect on joints.The results showed that pavement slab size had a significant influence on the maximum tensile stress of X-direction and Y-direction in the slab, the maximum value was 3.5 to 5 times than the minimum value at the same direction. There was a significant difference in the load transfer ability among pavement slabs with different sizes at tongue-and-groove joints. Therefore optimization objects were proposed.
