摘要
采用理论计算与现场实测相结合的方法 ,在上海市轨道交通明珠线的高架桥桥梁主体结构竣工后到浇注承轨台之前的这一时段对实桥的徐变变形进行观测、分析 ,从而对浇注承轨台的徐变变形终极值作出估算 。
There is a creep deformation on the viaducts of rail transit from the completion of bridge main structures to the concreting rail-support stage. By combining theoretic calculation and worksite survey, the author argues that the value of creep deformation of the rail-support could be estimated, which will finally direct the later stage of the construction.
