智能型全站仪三维坐标测量法在超高层建筑高程检核中的应用
|
摘要
为解决超高层建筑施工过程中的标高控制难题,介绍一种三维坐标法引测高程技术,即利用高精度全站仪的极坐标测量方法,通过其高精度的测角和测距功能,将仪器上的计算程序转换为观测点位的三维坐标,再通过测量中的上、下观测点的坐标差计算高程,此方法是对传统的天顶测距法进行的改进,经实践,引测精度较高且操作更为简便。
In order to solve the elevation control difficulties in the construction process of super high-rise buildings,a 3D coordinate measurement technology is introduced to perform elevation measurement,that is,the polar coordinate measurement method by using high-precision total station is adopted,and through its high-precision angular and distance measurement functions,the calculation program of the instrument itself is converted into the 3D coordinates of the observation points,and then the elevation is calculated by the coordinate difference between the upper and lower observation points.This method is an improvement of the traditional zenith distance measurement method,and through practice,it has higher measurement precision as well as simpler and easier operation.
