Research On Swivel Construction Monitoring And Control Technology For T-shape Rigid Frame Bridge

The rapid development of economy has led to the rapid development of traffic.More and more bridge structures are needed.Rapid,safe and stable become the main development direction of bridge structure construction,and also force the bridge construction technology to continue to develop and progress。On the ground of the T-shape rigid frame,We use MIDAS software to set up the finite element model which is used to analyze the whole construction process.The paper also studies the composition,installation,steps and influencing factors of the swivel system of swivel construction,and comprehensively demonstrates the problems of the swivel system in construction and analyzes them.We use MIDAS software to set up the finite element model which is used to analyze the whole construction process.We get the stress and deformation in cantilever construction process.We laid concrete,temperature sensors and the height measuring point under the program in the bridge.Deflection and stress are abserved,we analysis the structure data so as to provide a reasonable and proper guidance for the construction.The comparison of two counterweight schemes and the calculation methods of each parameter under different schemes are given.We need to have a balance weighing test to get the unbalanced torque,friction coefficient and so on.So we can take the weight measures to ensure that the rotating bridge will swivel smoothly.
