| Abstract: | With the T-beam bridge of the Yichang-Wanzhou double-line railway as a practical example,whose piers are 108 meters in height and 116+116 meters in span,a train-bridge system coupling vibration analysis model is established in the paper.The results of the varying vibration-time-response of the train-bridge system in six different circumstances are calculated.With the targets concerning the safe,comfortable and steady operation of the train taken into account,the reliability in the use of railway bridges in ... |
