空间球体建筑变形检测新方法

使用高精度全站仪检测了上海某球体结构的变形情况,并运用自由设站采集均匀分布在球体上的点位坐标,通过坐标转换将球体点坐标统一到一个坐标系;同时根据空间向量球的中垂面性质,采用一种新的空间球体拟合方法,对球体点坐标进行处理,以解算出球心坐标、半径,进而反算出球体变形情况。

New deformation detection method of buildings with spatial sphere

The paper detects the deformation conditions of the spatial sphere structure in Shanghai city by applying high-accuracy total station, collects the point coordinate distributed equally on the sphere by setting free-station, and adjusts the sphere point coordinates to the only coordinate through coordinate transformation. According to the middle vertical property of spatial vector sphere, it applies new spatial sphere simulation method, deals with the sphere point coordinate, obtains the sphere center coordinate and diameter, and finally calculates the sphere deformation conditions.
