摘要
针对装配式预应力混凝土空心板桥,利用各向异性线弹性理论和三维有限元的方法,构造了一种正交各向异性接触模型,模拟铺装层与桥面板之间的接触情况,并考虑铺装层厚度的影响,对层间剪应力进行了力学计算与分析,为设计与施工提供依据.
To the assembling type of prestressed concrete hollow board bridge.By using the anisotropy theory and the three-dimensional finite element method,a contact model of anisotropy was constructed.Contact stresses between the bridge panel and bridge deck were calculated with considering the influence of the thickness of bridge deck.The results can be used to instruct to design and construct the bridge deck.
