地铁运行振动规律及减振措施
|
摘要
通过对轨道和车辆结构的分析,对引起地铁运行振动的原因和振动的传播规律进行了系统地研究.在此基础上重点从振源、受振建筑物和振动传播途径3个方面提出了切实可行的减振避振措施.提出降低车辆簧下质量、采用非摩擦式制动的径向转向架、铺设重型无缝钢轨对降低轮轨间垂向力具有重要作用;铺设浮置板轨道、使用轨道弹性扣件、构筑隔振沟可以控制乃至阻断振动的传播途径;对地铁线路附近的建筑物需要进行减振隔振处理.
The reasons of vibrating,regulations of propagation are studied systematically throughout analyzing the construction of rail and vehicle in this paper.Based on those mentioned above,some practical methods of vibration controlling are recommended on vibration resource,buildings and the way of propagation.By reducing the weight below the springs,adopting radial bogie with non-rubbing braking,laying seamless and heavy-duty steel rail,the force between rails and wheels can be decreased effectively.By adopting elastic fastener,laying SSFST,building vibration isolation trench,the propagation of vibration can be controlled or interdicted.And vibration isolation design is necessary for the buildings near the subway.
