摘要
以标准轴载为基本荷载,借助ANSYS结构有限元分析程序,用数值模拟的方法分析揭示了在铺装结构体系整体受力的情况下铺装结构层的弯拉应变大小、分布规律及其与正交异性板构成的关系,对钢箱梁桥面铺装结构体系的优化设计具有一定的应用参考价值。
Taking the standard axle load as basic load, with the help of ANSYS, the analysis has been done in this paper to reveal the strain bending size and distribution laws of pavement structure layer in the con- dition of overall stress to the pavement structure system and the relationship with orthogonal anisotropic plate, which has a certain practical reference value to the optimization design of steel box girder deck pavement struc- ture system.
