中文摘要：
以在建的深圳平安金融中心为工程背景,进行了施工阶段的健康监测与施工全过程模拟研究。施工阶段健康监测以结构的竖向变形、关键部位应力以及荷载监测为主,施工全过程模拟根据实际施工进度并考虑材料的时变效应对结构进行有限元建模分析。结果表明：核心筒的累计竖向变形大于巨柱,累计竖向变形与所处施工阶段和结构高度有关,施工压缩预调方法可以有效补偿结构的累计竖向变形;结构应力随着施工的进度而均匀变化,上部结构每施工1层,核心筒压应力约增加0.09MPa,巨柱压应力约增加0.11MPa;在实测荷载作用下,结构层间位移角满足规范要求,结构在施工阶段是安全稳定的;模拟分析结果与实测数据吻合较好,可为类似工程提供参考。
英文摘要：
Ping＇an Financial Center in Shenzhen was selected as the project background,health monitoring and simulation study were carried out during the whole construction stage.The health monitoring in construction stage mainly included vertical deformation of the structure,stress of the key parts and load monitoring.The whole process of construction was simulated considering actual construction schedule and time-dependent effects of material.The finite element model analysis of structure was carried out.The results show that the cumulative vertical deformation is related to construction stage and structure height,and the cumulative vertical deformation of core-tube is larger than mega column.Construction compression presetting can effectively compensate the deformation of structure.The stress of structure gradually changes with the construction stage.The compressive stress of core-tube and mega column increase about 0.09,0.11 MPa respectively when one storey of upper structure is built.The inter-story displacement angle can satisfy the requirements of national standard under the action of measured loads,and the structure is in stable state during construction.The simulation results agree well with the measured data.The method proposed can provide reference for similar projects.
