摘　　要：运用ANSYS有限元软件,对桥面铺装层的应力受油毛毡防水粘结层厚度变化的影响进行分析。通过对三跨等截面混凝土连续箱梁桥进行有限元建模分析,确定桥梁最不利荷载作用位置,并得出粘结层厚度变化的影响情况。结果表明:粘结层与下层沥青铺装间应力随着油毛毡厚度的增加而增大,上下沥青铺装层间及上层沥青铺装层表面的应力则随之减少。The ANSYS FEM software is adoted to analyse the influence of the variation,in asphalt felt water-proof bonding layer thickness,on stress of bridge deck pavement layer.By building and analyzing the finite-element analysis model,for the three-span concrete continuous box girder bridge,there presents the most unfavorable loads positions acting on the bridge.And the influence of the adhesive layer thickness variation,is obtained.The results indicated that,with the thickness of asphalt felt increases,stress between bond coat and lower asphalt layer increases;While it decreases between the upper and the lower asphalt layer,also between the upper surface layer.
