| 摘 要： | 通过有限元分析方法,根据线弹性理论和层状体系理论,对钢箱梁桥面铺装层的弯拉应力、主剪切应力在层状结构间沿特征分析路径的分布及其沿层深的变化进行了计算与分析,确定了最大弯拉应力和最大层同剪切应力层位及其量值.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.

| Abstract: | The mechanical response of pavement layers on the orthotropic steel deck under wheel loading is analyzed by finite element method, based on liner elastic theory and layer theory. The distribution and numerical value of the draught stress and the main shear stress on layers are determined in the file. The results can provide a theoretical base for the paving design of orthotropic steel deck. |
