摘要
以北京地铁7号线为例,介绍了在复杂地质环境中,运用三维激光扫描技术对隧道开挖的现状进行测量,确定隧道的超欠挖情况,并监控隧道施工的风险,以防发生隧道塌方事故等的一种新方法,可广泛用于地铁及其他行业的隧道断面测量等相关施工工程中。
Taking Beijing Metro Line 7 as an example,this paper introduces a new method by using three-dimensional laser scanning technology to measure the present situation of tunnel excavation in the complex geological environment,to determine the overbreak and underbreak of the tunnel,and to monitor the risks of the tunnel construction to prevent the occurrence of tunnel collapse accident,etc.The method can be widely used in tunnel section measurement and other related construction projects in metro and other industries.
