摘要
根据线弹性理论和层状体系理论,用有限元分析方法对钢箱梁桥面铺装层的弯沉量、层顶弯拉应力、粘结层与桥面板结合处的主剪切应力的分布与变化进行了计算与分析,确定了最大弯沉量、最大弯拉应力和最大层间剪切应力的产生位置及其量值。研究结果可以为大跨径钢箱梁桥面柔性铺装设计提供理论参考。
The mechanics response of pavement on the orthotropic steel deck under wheel loading is analyzed, by finite element method, based on linear elastic theory and layer theory. The distribution and numerical value of the decline and draught stress also with the main shear stress in certain layer location are obtained in the file. The results can provide the theoretical base for the paving design of orthotropic steel deck.
