摘要
为研究高架轨道交通运行时的车辆与桥梁振动,以南京地铁1号线南延线某区间列车运行出现竖向振动异常为工程背景,对列车过桥引起的车桥振动状态进行了相关的理论分析,给出了车桥共振的条件,对车桥耦合振动进行了仿真模拟计算,并结合计算结果分析了不同影响因素对车桥振动的影响。通过综合各种分析,对过桥时列车的安全性、舒适性及桥梁结构的动力特性有了全面了解,并提出了相应的振动控制措施。
In order to study the train-bridge vibration induced by viaduct rail transit,according to the abnormal vertical vibration on the south extension line of Nanjing metro Line 1,a related theoretical analysis is carried out for the train-bridge vibration caused by passing trains,the reasons are discussed and the train-bridge coupling vibration is simulated.Based on the simulation calculation,the effective factors on train-bridge vibration are detected.Through comprehensive analysis,the safety and comfort of train,the dynamic property of bridges are fully understood,corresponding vibration control methods are proposed.
