摘要: 在长期运营过程中,受超长荷载和材料老化等因素的影响,超高层结构稳定性及承载能力逐渐降低,易发生安全事故。因此,必须对超高层建筑进行实时变形监测,了解其健康状态。以山东国际金融中心和云鼎大厦为研究对象,融合地基真实孔径雷达(GB-RAR)技术、双轴倾角传感器和GNSS技术等,从多维度监测超高层建筑动态变形特性;并基于手持和站式LiDAR技术实现山东国际金融中心室内外融合建模,搭建超高层建筑变形监测及预警可视化平台。结果表明,GB-RAR测量精度达0.016 5 mm,能够满足变形监测的精度要求。山东国际金融中心变形规律呈现摆动+振动协同演化的时空特性,摆动主方向为东南-西北方向,摆动周期约为20 d。400 m处摆动幅度约为180 mm,平均摆动速度约为1.5 mm/h。330 m处为平衡超高层结构偏心轴力的结构转换层,摆动幅度约为551 mm,平均摆动速度约为5.19 mm/h,是导致超高层建筑整体空间状态在S形、双曲线形和斜线之间来回切换,从而呈现非线性弹性变形特征的重要原因。

Abstract: During long-term operation,factors such as prolonged loading and material aging gradually reduce the stability and bearing capacity of super-tall structures,making them prone to safety incidents.Therefore,it is essential to conduct real-time deformation monitoring of skyscrapers to understand their health status.This study takes the Shandong International Financial Center and the Yunding duilding as research objects.It integrates technologies such as ground-based real aperture radar(GB-RAR),dual-axis tilt sensors,and GNSS technology to monitor the dynamic deformation characteristics of the super-tall structures from multiple dimensions.Furthermore,the study achieves the indoor and outdoor integrated modeling of the Shandong International Financial Center based on handheld and station-based LiDAR technology,establishing a skyscraper deformation monitoring and early warning visualization platform.The results indicate that the GB-RAR measurement accuracy reaches 0.016 5 mm,which satisfies the precision requirements for deformation monitoring.The deformation pattern of the Shandong International Financial Center exhibits a spatio-temporal characteristic of sway and vibration synergistic evolution.The main direction of the sway movement is from the southeast to the northwest,with a sway period of approximately 20 d.The sway amplitude at a height of 400 m is about 180 mm,and the average sway velocity is approximately 1.5 mm/h.The structural transfer floor,located at 330 m,balances the eccentric axial force of the super-tall structure.This floor exhibits a sway amplitude of approximately 551 mm and an average sway velocity of about 5.19 mm/h.This transfer floor is a key factor causing the overall spatial state of the skyscraper to switch back and forth among S-shaped,hyperbolic,and diagonal configurations,thereby presenting non-linear elastic deformation characteristics.
