地震作用下深水高墩刚构桥梁的动力响应分析
|
摘要
高墩大跨连续刚构桥梁的抗震性能是桥梁设计人员重点关注的问题.当高墩处于深水之中,由于桥墩外围的水和桥墩体内的水将由于震动而同时对桥墩产生作用,对其进行动力响应分析更为困难.在计算墩水耦合效应时采用Westergaard理论,对一座连续刚构桥梁的地震动力响应进行了反应谱分析和时程分析.研究结果认为考虑墩水耦合效应后,桥梁的地震动力响应的变化不明显.
Earthquake resistance property of long span rigid frame bridge with high-rise piers is important for bridge designers.It is very difficult to analyze dynamic response of such bridge if it was in deep water.Vibrating water which is around pier or in pier affect bridge in earthquake.Westergaard theory was used to analyze coupling vibration of pier-water.Earthquake response of a continuous rigid frame bridge was calculated by response spectrum method and time-history method.The conclusion is that earthquake response of bridge changes little considering coupling vibration of pier-water.
