摘要

为克服常规基坑围护结构变形监测方法涉及设备多、布点要求高、所需观测人员多、监测成本大、测斜管一旦破坏很难恢复的弊端,提出基于测量机器人开发深基坑自动监测系统,实现对深基坑围护结构体三维位移的自动监测,并对测量机器人开发自动控制软件需注意的问题及控制流程做了阐述。通过对监测网的布设、测量方法与程序流程、系统误差及系统构成的研究分析及在实际项目中的应用表明: 在无支撑结构通视条件较好的深基坑监测中,用测量机器人代替经纬仪、全站仪人工测量、测斜仪、分层沉降仪实现围护结构的整体监测是可行的,可节约监测成本,提高监测效率;另外,当测斜管被破坏时,可以作为补充手段,监测基坑不同深度的水平位移。

Abstract

Automatic monitoring system based on robot total station is developed. Points to which attention should be paid in the developing of the automatic monitoring system and the control process are presented. The analysis on the layout of the monitoring network, the monitoring method and process, the system errors, the system components and the application of the technology show that: 1) In the monitoring of deep foundation pits with good visual conditions, monitoring by robot total station is feasible, which can reduce the cost and improve the monitoring efficiency. 2) In case the inclinometer is destroyed, robot total stations can be adopted to monitor the horizontal displacement of the foundation pit at different elevations. 
