| 摘 要： | 文中结合我国当前的沥青路面设计方法,运用"反算当量路基回弹模量"法,把钢桁架混凝土桥桥面铺装结构倒置后,转换成普通路面的半无限空间层状弹性体系,并提出类似一般沥青路面设计方法的钢桁架混凝土桥桥面铺装设计方法。该法以铺装层顶表面最大拉应力(拉应变)作为设计控制指标,对桥面铺装结构层的设计有一定指导意义。

| Abstract: | Combined with the current method of asphalt pavement design in China,this paper uses inverse equivalent modulus of subgrade resilience to transform the inverted paving structure of steel truss concrete bridge into the semi-infinite space layered elastic system of common pavement,and puts forward the design method for bridge floor pavement of steel truss concrete bridge,which is similar to the method for general asphalt pavement.This method has a certain guiding significance to the design of bridge floor paving structure,with the maximum tensile stress（tensile strain） on the top of pavement as a control indicator. |

| Keywords: | bridge floor pavement inverse calculation modulus of resilience steel truss stress |
