Research of irregular super high-rise building verticality measurement method

超高层建筑垂直度测量成果是质量验收及偏差处理的重要参考依据,而超高层建筑的动态特性和非规则性在一定程度上增加了垂直度测量的难度。文中提出一种非规则性超高层建筑垂直度测量方法:采用智能全站仪监测系统进行超高层建筑周日摆动监测,利用GPS方法从宏观上分析测量基准的可靠性和准确性,采用静力矩方法计算垂直度偏差。应用实践表明,这种方法有效解决了施工控制网竖向传递倾斜偏差改正这一关键性技术难题,保障测量基准的准确性和可靠性,垂直度偏差的计算与表达是科学合理的,具有借鉴意义。

The result of super high-rise building verticality measurement is an important reference for the quality inspection and deviation processing.The dynamic characteristics and irregularity of super high-rise building increase the difficulty of verticality measurement to a certain extent.This paper proposes an irregular super high-rise building verticality measuring method:measuring robot method is used for daily deformation monitoring for super high-rise building.The GPS method is used for internal and external compliance check of control network.The static moment method is used for the calculation of verticality deviation.The practical application result shows that the method is effective for the critical technical problem of tilt deviation correction of vertical transmission of construction control network.The accuracy and reliability of the measurement datum are guaranteed.The calculation and expression of verticality deviation are scientific.
