Abstract: The characteristics of quasi-rectangular shield tunnel are analyzed. The differences are contrasted and analyzed with the traditional circular shield tunnel. The construction measurement methods of quasi-rectangular shield tunnel are optimized. Three-dimensional laser scanning technology is introduced to measure the section, which solved the problem that the common section scanning technology could not accurately extract the center of the single side tunnel, The measurement and extraction of quasi-rectangular section are successfully completed.

Key words: quasi-rectangular, shield tunnel, construction survey, optimization, 3D laser scanning
