Article Preview

The detection meaning of section outline on highway tunnel and the principle and operation method of laser measuring instrument of tunnel section are introduced in this paper; Aiming at the quality inspection and evaluation content for highway, the laser measuring instrument of tunnel section is used to inspect the geometry of tunnel outline. The inspection data on axis deviation, width, vaults height and arch waist height of tunnel are obtained by calculation of polar coordinates and cartesian coordinates gotten by instrument scanning. Compared the inspection data with design data, we can judge whether the tunnel meets the requirements. According to this method, the tunnel outline of Sai-Guo highway meets the basic requirement.
