摘要
介绍了陀螺全站仪在地铁竖井联系测量中的应用。简述井上下连接测量、陀螺全站仪定向的方法,分析陀螺定向的精度,讨论定向方法的优缺点。实践表明:利用陀螺全站仪进行竖井联系测量,克服了几何定向精度低、占用井筒时间长等缺点,提高了井下测量数据精度,为地铁安全生产工作提供了保证。
This paper introduces the application of gyroscope total station in subway connection survey.It briefly introduces the method of connection survey and gyroscope total station orientation,analyzes the accuracy of gyroscope orientation,and discusses the advantages and shortcomings of the method.Practice proves that shaft connection survey utilizing gyroscope total station overcomes the shortcomings of low accuracy and long period of shaft occupation of geometric orientation,improves the accuracy of underground survey data,and provides support for subway production security.
