摘要
应用有限元方法,对在车辆荷载作用下的桥面铺装结构体系中的沥青混凝土面层和其下的防水层进行剪应力计算,并且计算分析了改变沥青混凝土面层厚度、弹性模量和泊松比等参数对防水层剪应力的影响。依据计算结果提出了在以抗剪强度为验算指标的桥面沥青混凝土铺装设计方法中关于抗剪强度指标的建议。
The finite element method is used for calculating the sheafing stress of asphalt concrete surface and waterproof layer of the bridge deck pavement under vehicle load. The effects of changing the parameters such as thickness, modulns and Poissn＇ s ratio of concrete surface on the sheafing stress of waterproof layer are calculated and analyzed. Some suggestions about the sheafing stress criterion for bridge deck asphalt concrete pavement design are provided based on the calculation results.
