摘　　要：平安国际金融中心总高599米,在建筑物施工及运营过程中,由于外界环境(日照、风、温度等)及建筑物自身的影响,建筑物的摆动影响大。文中通过自主研制的北斗兼容的接收机,对建筑物关键点位进行静态观测,在数据处理中,自主研制了卫星定位的整周模糊度回代高精度单历元定位算法,利用10Hz采样解算数据,获取大楼在荷载下平面变形,根据测定的大楼的变形值和摆动情况,指导施工进行归心改正,确保大楼的垂直度。Ping′an international financial center,the total height of 599 meters,in the process of building construction and operation,due to the external environment（sunlight,wind,temperature,etc.）,and the building itself,the motion of the building occur.Developed in this paper,through BDS compatible receiver,the key point for static observation of the building,in data processing,independently developed a whole week of satellite positioning ambiguity back to the generation of high precision single epoch positioning algorithm,using 10 hz sampling calculating data,access to the building plane deformation under load,according to the determination of the deformation value of the building and oscillation situation,guide the construction to carry on the correction for centering,ensure the verticality of the building.
