正交异性钢桥面铺装层的力学特性分析

Mechanical analysis of pavement of orthotropic steel deck

分析在不同的荷载位置下 ,对应不同沥青混凝土模量值的正交异性钢桥面铺装层的应力应变特性及与钢板的粘结性能。通过分析 ,确定最不利加载位置和铺装层材料的各项力学指标 ,如铺装层材料最大容许拉应力、最大容许拉应变以及粘结层材料的剪切强度等 ,作为铺装层材料参照标准 。

The stress strain properties of orthotropic steel deck pavement and adhesive performance between pavement and steel deck are analyzed under various modulus of asphalt concrete and load case.Based on the analysis, the worst case load location and the mechanical indexes of pavement material are determined, including the maximum allowable tensile stress,tensile strain and shear strength of adhesive layer material, which can be served as reference standards of pavement material in order to search the suitable pavement project.4 tabs,8 figs,7 refs.
