Based on the measuring tower positioning system of Hongkong-Zhuhai-Macao Bridge immersed tube installation, through the control installation and calibration, accuracy analysis, construction-location, total station instrument calibration, fast static detection, data processing, and breakthrough measuring review, we analyzed the successful application of measuring tower method in the construction of large-scale immersed tube installation in deep groove at deep water area. Proved by the engineering practice, the method can realize all-weather continuous operation, high positioning precision, strong reliability in real data. It is worth of popularization in accurate positioning and installation of large-scale components.
