摘要
轨道交通引起的地面振动是由列车在轨道上的移动造成的。将地铁、铁路和有轨电车产生振动的主要机理归纳为六类:准静态、参数激励、钢轨不连续、轮轨粗糙度、波速和横向激励,详细分析了轨道交通的环境振动激励机理。
Significant ground vibration near rail systems is attributed to trains moving along the track. There are six main mechanisms for the generation of vibration from metro,railway and tram: quasi-static,parametric excitation,discontinuities of the rail,wheel/rail roughness,wave speed and lateral excitation. These mechanisms are discussed in detail,a better understanding of environmental vibration excitation mechanisms from rail systems is developed.
