- Abstract:
- The important parameters that influence the mechanical property of the paving layer on an orthotropic steel bridge deck are the paving layer thickness and modulus of the asphalt concrete surfacing. Three important indices that control the typical failures of the paving layer are the maximum tensile stress of paving layer, the maximum shear stress between the steel deck and the paving layer, and the maximum deflection on the paving surface. In this paper, the analytical model of paving systems on orthotropic steel bridge deck is established, and the finite element method is adopted to study the stress and strain of paving system. With the variation of asphalt concrete modulus in high or low temperature season, the influences of paving layer thickness on three control indices are researched. The results provide a theoretical basis for the determination of thickness of the paving layer on the steel bridge deck.
- 影响正交异性钢桥面铺装层力学性能的重要参数有铺装层的厚度和沥青混凝土铺装层的模量.铺装层典型破坏的3个控制指标是铺装层的最大横向拉应力、钢板和铺装层间的最大剪切应力和铺装层的最大挠度.本文建立正交异性钢桥面铺装体系分析模型, 用有限元方法进行了铺装体系的受力分析, 研究在高、低温季节沥青混凝土模量变化的情况下, 不同铺装层厚度对三大控制指标的影响.研究结果对钢桥面铺装层厚度的确定提供了理论依据.
