Scheme Research of Adding Noise Barrier to Existing Bridge Adopted by Passenger-dedicated Line |
| |
| Abstract: | Combined with noise control project of Beijing-Shijiazhuang Passenger-dedicated Line,aiming at the unsafe problems in bridge structure produced by adding the noise barrier to the existing bridges,the author proposes three solutions,including the scheme of strengthening the existing bridge,the scheme of steel structure anchored into ground,and the scheme of concrete beam anchored into ground.After that,the author expounds the structural details of each scheme,and provides the comparison results about the vulnerable points and advantages and disadvantages of the structure in each scheme.These design schemes can provide reference for similar railway noise barrier project. |
