Abstract: Monitoring the deformation of the tunnel structure during the iron operation phase to ensure the safety of the subway operation. Ellipticity detection is an important task in the detection of subway tunnel structures. This paper briefly introduces several methods of traditional ellipticity detection, analyzes the basic principle of the new mobile 3D laser scanning detection system and the method and processing flow of tunnel ellipticity detection. Through the practical application of the engineering case and comprehensive analysis of the test results, the great advantages of the mobile 3D laser scanning technology in the ellipticity detection of the segment are proved, and the development of the tunnel structure inspection industry is promoted.

Key words: deformation monitoring, ellipticity detection, moving 3D laser scanning, shield segments
