| Abstract: | 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. |

| Keywords: | three-dimensional laser scanning technology tunnel metro section measurement overbreak and underbreak |
