摘　　要：为研究单向收进超高层结构在施工阶段的水平变形规律,针对单向收进的超高层结构进行施工阶段结构水平变形实测。结果表明,结构在58层以上的水平位移突然增大,在收进处水平变形方向发生突变;收进处71M层核心筒水平位移方向与结构收进方向一致,核心筒平均水平位移最大值为72.18mm(向东)和66.36 mm(向北);外框柱的水平位移方向与结构收进方向相反,水平位移最大值约为76.81mm(向东)和69.22mm(向南);根据测点的水平位移变化趋势,单向收进超高层结构在施工阶段的水平变形方向与核心筒收进方向一致。In order to study the horizontal deformation law of unidirectional retracted super high-rise structure in the construction stage,the horizontal deformation of a unidirectional retracted super high-rise structure was measured in the construction stage.The results show that,the horizontal displacement of the structure above 58 floors suddenly increases,and the horizontal deformation direction changes suddenly at the retraction.The horizontal displacement direction of the core tube on the 71M floor is consistent with the retraction direction.The maximum average horizontal displacement of the core tube is 72.18mm(eastward)and 66.36mm(northward).The horizontal displacement direction of the outer column is opposite to the retraction direction,and the maximum horizontal displacement is about 76.81mm(eastward)and 69.22mm(southward).According to the variation trend of the horizontal displacement of the measuring points,the horizontal deformation direction of the unidirectional retracted super high-rise structure in the construction stage is consistent with the retraction direction.
