摘　　要：根据结构组划分层数、停工时间、是否考虑混凝土收缩与徐变效应建立不同的施工模型,对比分析停建续建高层建筑竖向变形规律,并对竖向变形影响因素进行分析。研究结果表明,停建续建建筑竖向变形分布规律与非停建建筑有所不同,停建续建建筑已建结构最高处变形达最大值,而续建结构变形呈两端小、中间大的分布规律。在不同层数组成结构组的条件下,随着结构组内划分层数的增加,高层建筑竖向变形理论计算结果误差越大,且误差与所处结构组内位置有关,处于结构组越低的位置,竖向变形理论计算结果越接近基准值。Based on the structural groups division layers,downtime and whether the effects of concrete shrinkage and creep are considered,different construction models are established.The vertical deformation law of tall buildings with suspended and continued construction is compared and analyzed,and the influencing factors of vertical deformation are analyzed.The research results show that the vertical deformation curves of buildings under suspended and continued construction as the number of layers increases differs from that of non-suspended buildings.The maximum deformation occurs at the highest point of the existing structure of the suspended and continued construction buildings,while the deformation of the continued structure shows a distribution pattern of smaller at both ends and larger in the middle.Under the condition of different structural groups composed of various numbers of layers,as the number of structural groups division layers increases,the error in the theoretical calculation results of vertical deformation becomes larger,and the error is related to the position within the structural groups.The lower the position within the structural groups,the closer the theoretical calculation result of vertical deformation is to the reference value.
