摘要

现代交通对大跨径钢箱梁桥面正交异性板的铺装材料提出了更高的要求.以改性沥青SMA铺装材料为例

应用有限元方法分析了该材料在钢桥面铺装应用中的力学行为.建立了钢桥面铺装的简化计算模型

分析了该材料在钢桥面铺装中随着不同轮载模型作用下各个主要力学指标的变化规律

重点考察了轮载加载方式对分析结果的影响.通过计算分析确定了更切合实际的车轮荷载施加方式

以及该材料在钢桥面铺装中的横向最不利荷载位置.分析指出:单轮荷载模型与双轮荷载模型计算结果有比较大的差别

双轮加载模式更能反映实际轮压作用.

Abstract

Modern transportation demands the material better properties in the pavement on the box girder of the steel bridge.Taking the modified asphalt SMA as an example of a pavement material

the finite element were used to analyze the mechanics properties of the material on the steel bridge deck.With an established simplified model including the steel bridge deck system and the pavement

the variations of the main mechanics indexes of the pavement in different wheel loading models were analyzed

and the effects of the loading modes of wheel on the analyzing results were investigated.After analysis

a more reasonable model of the wheel load was recommended

and the most destructible position of the loading was determined.The analysis shows that the difference of results from the two models of single wheel load and double wheel load is remarkable

and the model of double wheel load can reflect the actual wheel load better.
