STUDY ON KEY TECHNOLOGY AND CONTROL TECHNOLOGY FOR CANTILEVER CASTING CONSTRUCTION OF CONTINUOUS BEAM BRIDGE OF HIGH-SPEED RAILWAY
Based on the construction of the newly built grand bridge in Xiaoshifang Village in Heibei,part of the high-speed railway from Xiong'an New Area to Xinzhou,a control method for symmetrical basket type cantilever casting of prestressed concrete continuous beams of high piers was elaborated.In addition,the internal force and deformation of the main beam was controlled by one-site monitoring and measurement.Results of this study can be referenced for cantilever casting control of continuous beam bridges of high-speed railways.
