摘要
本文就城市轨道交通的隧道结构断面的测量方法进行了研究,提出了一种采用地面激光扫描仪技术的测量方法,研究了此方法的主要工作流程、基本原理和方法。把此方法用到天津城市轨道交通二号线工程,使用地面激光扫描仪测量隧道的结构断面,其精度和效率较常规仪器和方法都有显著提高。
The paper researched the method for surveying tunnel structure profile of city track traffic with ground laser scanner technology. It mainly studied its nihin work flow, basic principle and method, and adopted it to the Second Line Engineering of Tian- jin City Track Traffic. Its outcome manifested that it could get higher precision and surveying efficiency using ground laser scanner to survey tunnel structure profile than normal surveying instruments.
