摘要
着重介绍转站测量技术的基本原理及作业流程,并将此技术方法应用于地铁深基坑桩顶水平位移监测中,从而实现对复杂条件下基坑水平位移的高精度监测。实践表明,该技术方法具有监测精度高、范围广、操作灵活、适应性强、工作效率高等优点,还可进一步推广应用到复杂外形的建/构筑物的三维变形监测。
This paper elaborates the principles and technical process of transfer station surveying which can be applied to pile top horizontal displacement monitoring in a subway foundation pit. Results showed that the method has the advantages of high monitoring precision, wide range, flexible operation, strong adaptability and high working efficiency, and can be widely applied to 3D deformation monitoring of structures with complicated configuration.
