Title: Analysis of bridge lateral rigidity for new Xinzhen Bridge
Abstract: The lateral amplitude of pier exceeds ordinary value given by code for rating existing railway bridges,when speed-raised train passes through the new Xinzhen Bridge.Whether the lateral rigidity of the bridge satisfies the requirement of running train needs to be answered.The computing model for train-bridge system vibration was presented,and the safety of running train on the bridge was analyzed with energy random analysis theory for derailment.On condition that train will not derail,the smoothness of running train on the bridge is analyzed.The results show that train can pass through the bridge safely within the speed of 80 km/h and the smoothness of train satisfies corresponding code.The relationship between ordinary value of pier and safety of running train is discussed,and it is unreasonable to regard the ordinary value of pier as the limit value of traffic safety.
