摘要
根据线弹性理论和层状体系理论,用有限元法计算分析了正交异性钢桥面系梯形闭口肋厚度对桥面铺装层承载性能的影响效应,并给出了加劲肋厚度的建议取值及正交异性钢桥面系的优化设计方案.研究结果可以为钢箱梁设计及桥面铺装设计提供理论参考.
Trapezoid rib is widely used in orthotropic deck, the rigidity of rib is very important for mechanics performance of box girder and deck pavement. If rib＇s section is confirmed, the thickness of rib wall is the most important parameter for rib＇s rigidity. The mechanics response of pavement on the orthotropic deck with series rib-wall thickness under wheel loading is analyzed by finite element method, based on linear elastic theory and layer theory. Reasonable rib-wall thickness is advised and optimized the design project is offered here. The results can be a reference for box girder and orthotrooic deck pavement design.
