Discussion on the Measurement Method and Software Development for the Cross Section of Circular Tunnel in Subway
During the construction of urban subway tunnel,section measurement and detection are required. In this paper,an improved to-tal station survey method is proposed for the current commonly used circular tunnel section survey method. At the same time,a new section fit-ting algorithm was proposed and corresponding software was developed,which was verified through actual engineering data. The results demon-strate that the proposed method and algorithm have high feasibility and accuracy,and can be applied to practical projects.
