摘　　要：以在施工的深圳平安金融中心为研究对象,在结构关键楼层布设光纤光栅应变传感器,实现对整个塔楼高度范围内竖向变形的全面监控。根据8种施工工况下的实测应变,采用线性插值法计算了塔楼各层的竖向变形,并采用有限元法进行了施工过程仿真分析,提出了结合实测数据和有限元模拟的同比例法验证了线性插值法的可靠性。结果表明,用于深圳平安金融中心的竖向变形监测方案可以对该结构竖向变形提供有效的监控,也可为其他超高层建筑竖向变形监测提供参考。Taking the Ping-an Financial Centre in Shenzhen during construction as the research object, the fiber grating strain sensor was arranged on the key floor of the structure to realize the comprehensive monitoring of the vertical deformation in the height range of the entire tower. According to the measured strain under eight construction conditions, the vertical deformation of the towers was calculated by linear interpolation method, and the finite element method was used to simulate the construction process. Moreover, a so-called same-proportion method which combined the field measurements with the results of the finite element analysis was proposed and implemented to verify the reliability of the linear interpolation method. The results show that the vertical deformation monitoring scheme for Ping-an Financial Centre in Shenzhen can provide effective monitoring of the vertical deformation of the structure, and can also provide reference for the vertical deformation monitoring of other super-tall buildings.
