基于桥梁整体变形的桥面铺装力学响应分析
Mechanical response analysis of bridge deck pavement based on overall deformation of bridge
摘要
Abstract
[Purposes]This paper aims to master the mechanical response law of asphalt pavement layers under the overall structural deformation of cement concrete bridge and guide the comprehensive design of asphalt pavement on the bridge deck.[Methods]The sub-model method was used to analyze the temperature stress of the asphalt pavement layer in the maximum negative bending moment area of the whole bridge model under three representative temperature conditions,and the load response law of the pavement layer under the joint influence of the overall deformation and local wheel load of the bridge was studied.[Findings]The changing trend of temperature stress of the pavement layer under different seasonal temperatures is the same,and the temperature stress decreases with the increase in pavement layer depth.Local wheel load acting on one side of the side beam is the most unfavorable transverse load position.The increase in horizontal force will increase the stress indexes in the pavement layer,especially the maximum tensile stress and maximum shear stress on the pavement surface.The increase in pavement layer modulus and thickness has different effects on the stress of the pavement layer,but it generally improves the shear condition between the pavement layer and the bridge deck.[Conclusions]In the structural design of bridge deck pavement,the effects of temperature and horizontal force should be comprehensively considered,and the reasonable selection of pavement materials and pavement layer thickness should be taken into account.关键词
