对大型不规则建筑的测量布控及其精密定位

本文针对上海国际体操中心大型不规则的、由双向曲面构成的建筑的施工测量实际，阐述了对其实施一系列测量布控等手段来保证整个建筑群的相对位置及其几何尺寸，并对体操馆顶面网架安装所需的96个预埋件实行分块控制，在现场范围内使所有点位精度均控制在2mm以内。

This paper describes that a series of methods in measuring arrangement and control are used to ensure the relative position and geometry size for actually measuring huge irregular,double-curve constructed and spherical building of shanghai international gymnasttes crnter,and the unity six prefab,that is needed in loading the construction of the Gym cell are segregatly controled,so that all position accuracy are limited within two millimeters at current spot.
