基于徕卡TM系列全站仪在变形监测中的应用与探讨
|
摘要
传统变形监测中,水平竖向位移观测费时费力,精度难于保证。通过徕卡TM系列测量机器人"后方交会设站+多测回测角"程序,完成水平竖向位移观测,大大提高观测效率,观测效果更佳。本文以某深基坑工程为例,采用徕卡TM系列测量机器人观测基坑水平竖向位移。"后方交会设站"在每次观测前重新交会解算设站坐标,消除设站点变形影响;"多测回测角"在完成设站后,即可调用进行自动观测,大大减少观测人员观测工作,减少观测时间,提高观测效率。
In traditional deformation monitoring, horizontal vertical displacement observation is time-consuming and laborious, besides the accuracy can' t be guaranteed. Through theprogramembed inLeicaTM series measuring robot which called " Resection station setup + Multi-observation Set and Angle", the horizontal vertical displace-ment observation is completed, which greatly improves the observation efficiency and improves the observation ef-fect.In the paper, taking a deep foundation pit project as an example, the LeicaTM series measuring robot is used to measure the horizontal vertical displacement of the foundation pit. The " Resection stationsetup" will calculate the station coordinates before each observation in this way to eliminating the influence of site deformation.After the completion of the station setup, the " Multi-observation Set and Angle" can be called to perform automatic obser-vation, which greatly reduces the observation work of the observers, reduces the observation time and improves the observation efficiency.
