A Method of Metro Tunnel Deformation Measurement Based on the Theory of Close Range Photogrammetry

Article Preview

Abstract:

In order to solve the difficulties in the deformation measurement of subway shield tunnel structure, a non-contact measurement method of close range photogrammetry technology based on movable base is put forward. A light metal frame is designed as the movable base, which is calibrated by the electronic total station. And the case study verified the feasibility of the measurement.
