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 applied to calculate the shear stress of asphalt concrete pavement and its waterproof layer in the bridge deck pavement structure under vehicle load. The influence of changing the thickness of asphalt concrete pavement, Songbi parameters such as waterproof layer shear stress. Based on the calculation results, some suggestions about the shear strength index are put forward in the design method of deck asphalt concrete pavement with the shear strength as checking index.
