摘要
针对超高层建筑多因素下易导致施工中主体结构倾斜的问题,以中国尊大厦结构施工中对同心(轴)度测量控制为例,介绍了折点坐标算法、等高比修正补偿技术,通过建立三维测量控制网,采用激光投影贯通测量技术,经复核,结构封顶后,同心(轴)度精度控制在5mm以内,满足规范及设计要求。
Aiming at the problem of inclination of main structure in construction of super high-rise building under multi-factors,taking the measurement and control of concentricity(axis)degree in construction of CITIC Tower as an example,the point coordinate algorithm and the compensation technology of equal height ratio are introduced.A three-dimensional measurement and control network are established and laser projection through measurement technology is adopted.Practice shows that after checking,concentricity(axis)degree of structure is sealed.The precision is controlled within 5 mm,which meets the requirements of specifications and design.
