| Abstract: | The paper summarizes and introduces in detail the structure,load system,type of reinforcement and vibration damping test under wheel load drop of resiliently supported long sleepers,which are firstly designed to meet the need of secondary vibration damping for part of Capital Airport Express. Compared with the traditional resiliently supported blocks,resiliently supported long sleepers possess the technical advantages of excellent stability and convenience for checking and replacing elastic pads. The techni... |
