1前言超高层建筑具有投资大、使用时间长、结构复杂等特点,对结构安全性、可靠性及耐久性要求较高,实时监测超高层建筑结构健康状况在建筑施工及使用过程中均具有非常重要的意义。施工期间承重构件的竖向变形差异会直接影响施工质量超高层建筑中混凝土材料受到徐变和收缩应力的影响,产生的弹性变形会有附加变形,并随着时 1 Introduction Super high-rise buildings with large investment, long service life, complex structure and other characteristics of the structural safety, reliability and durability requirements of real-time monitoring of super high-rise building structural health in the construction and use of the process are very Significance. Vertical deformation of load-bearing members during construction will directly affect the quality of construction High-rise buildings in concrete subjected to creep and shrinkage stress, the resulting elastic deformation will have additional deformation, and with time
