摘要
传统的地铁隧道断面测量方法外业操作复杂,内业计算繁琐,效率低下,数据质量不高,已不能满足现代化的地铁建设需要。本文结合北京地铁8号线三期工程,介绍一种隧道断面内外业一体化的方法,并给出了该方法的具体操作流程。此法可以简化断面测量的过程,实现断面测量外业测量和内业数据处理的自动化,极大提高工作效率和数据质量。
The traditional method of measuring the section of subway tunnel is complicated,the calculation of internal work is tedious,the efficiency is low,and the quality of data is not high,so it can not meet the needs of modern subway construction project.Combined with the Three phase of Beijing Metro Line 8,this paper introduces a method of interior and field work in subway tunnel section survey,and gives the concrete operation flow of the method.This method can simplify the process of cross section measurement,realize the automation interior and field work,and greatly improve work efficiency and data quality.
