江阴大桥钢桥面防水粘结层受力分析

Mechanical Analysis of Jiangyin Yangtze River Highway Bridge Waterproof and Cohesive Layer

江阴长江公路大桥采用正交异性钢箱梁结构,桥面铺装层在国内首次采用沥青玛蹄脂混凝土材料。将正交异性钢桥面板、铺装层、防水粘结层作为受力整体,建立有限元分析模型,研究荷栽作用位置、荷载类型、防水粘结层材料参数等因素对铺装防水粘结层受力的影响,为桥面铺装防水粘结层材料的设计与选择提供理论依据。

The orthotropic steel-girder structure is adopted in Jiangyin Yangtze River Highway Bridge,the mastic asphalt concrete is first used as pavement material in China.The finite element model is established in the paper uniting the orthotropic steel deck,asphalt pavement and waterproof and cohesive layer,The effects of load action positions,load types and waterproof and cohesive layer parameters on the stress and deformation of the layer are studied.The research provide the theoretic base for the design and choice of waterproof and cohesive layer material.
