Attitude control points of shield machines are important components of the guidance systems of shield machines and are the basis for the calculation of the initial parameters of shield machines and determination of the realtime attitude of shield machines. In order to perform surveying of the attitude control points of shield machines, survey models should be established, i.e., the 3D coordinates of the cutter head and the center of the midshield are calculated by means of accurate surveying of the outer diameters of the cutter head and the cylinder of themidshield by traverse survey method and trigonometric leveling method, after which the coordinate system of the shield machine is established. By means of calculating the 3D coordinates of the attitude control points in the coordinate system of the shield machine, the attitude of the shield machine is obtained. The application of the survey model in the survey tests on a shield machine manufactured by Herrenknecht A.G. for ShiPan running tunnel on line 3 of Guangzhou Metro demonstrates that, by means of the survey model, the attitude control points of shield machines can be calculated and the deformations of theshields can be detected.
