根據結構組劃分層數、停工時間、是否考慮混凝土收縮與徐變效應建立不同的施工模型，對比分析停建續建高層建筑豎向變形規律，并對豎向變形影響因素進行分析。研究結果表明，停建續建建筑豎向變形分布規律與非停建建筑有所不同，停建續建建筑已建結構最高處變形達最大值，而續建結構變形呈兩端小、中間大的分布規律。在不同層數組成結構組的條件下，隨著結構組內劃分層數的增加，高層建筑豎向變形理論計算結果誤差越大，且誤差與所處結構組內位置有關，處于結構組越低的位置，豎向變形理論計算結果越接近基準值。

Based on the structural groups division layers, downtime and whether the effects of concreteshrinkage and creep are considered, different construction models are established. The verticaldeformation 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 verticaldeformation curves of buildings under suspended and continued construction as the number of layersincreases differs from that of non?suspended buildings. The maximum deformation occurs at the highestpoint of the existing structure of the suspended and continued construction buildings,while thedeformation of the continued structure shows a distribution pattern of smaller at both ends and larger inthe middle. Under the condition of different structural groups composed of various numbers of layers, asthe number of structural groups division layers increases, the error in the theoretical calculation results ofvertical 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 verticaldeformation is to the reference value.
