Research on the Structural Design of Simply-supported Box Girder for 5-meter-high Sound Barrier in High-speed Railway
The general reference diagram of railway bridge is generally designed based on the sound barrier with conventional height,which is often unable to apply to the case of non-standard height sound barrier required by environmental protection.Based on the 32 meter standard double-line simply-supported box girder in high-speed railway,this paper studies the structural design of 5-meter-high sound barrier box girder.Through the finite element calculation,it is concluded that when the bridge deck is subjected to concentrated torque,using solid model for analysis can better simulate the stress distribution.For the setting of 5-meter-high sound barrier simply-supported box girder on the bridge,the appropriate reinforcement of the flange steel bar can meet the structural design requirements.
