This paper focuses on the key scientific problems of synchronous rotation construction with large angles and takes two T-shaped rigid frame bridges of the Wuyi Expressway over the Chengdu-Kunming Railway as the engineering background. Construction technologies of this project are introduced, including the installation process of spherical hinges, the design of the traction system, and the precision control method. Finite element models of the full-bridge were established to obtain the lateral unbalanced moment of the structure and the test method of the longitudinal unbalanced moment is shown in detail. Furthermore, the key parameters of SRM are analyzed and calculated, including the derivation and modification of the existing static friction coefficient calculation formula of the spherical hinge. Based on the measured data, the accuracy of different friction coefficient prediction formulas is evaluated.
