【Abstract】：Due to the issue of the traditional subway monitoring technology is unable to fully capture the structural deformation of the subway tunnel， this paper suggests that 3D laser scanning technology， which verifies the application of 3D laser scanning in subway operation monitoring through actual project as an example， compares and analyzes manual data with 3D laser scanning data. It concludes that 3D laser scanning demonstrates high accuracy and reliability in detecting subway tunnel deformations.

【Key words】：subway tunnel; 3D laser scanning; accuracy verification; monitoring
