Study on Running Performance of Train and Index of Traffic Safety of Shangbaipu Bridge

Abstract:

The running performance of train on Shangbaipu bridge is analyzed with energy random analysis theory for derailment. The calculated result shows that the running safety of train cannot be ensured with the existing operation condition, and the measurement of rate-limiting or reinforcement is needed to be taken for this bridge. A method for establishing index of traffic safety for railway bridge is proposed, and the detailed contents are as follows. The lateral amplitude on the middle of beam is determined as index for traffic safety for beam-pier system. The critical beam-pier system with which the running performance of train can be guaranteed is determined. The lateral amplitude of critical beam-pier system is calculated and determined as limit value for traffic safety. The limit value of lateral amplitude for traffic safety for Shangbaipu bridge is determined as L/4000.
