本文回顾，综合和基准有关铁路振动的新认识。首先评估了振动对乘客舒适度的影响，然后评估了振动对轨道性能的影响。然后讨论了地面振动及其对铁路附近建筑物结构响应的影响。讨论了最适合铁路振动仿真的数学和数值建模策略，以及缓解策略。对于地面振动，讨论了结构放大以及如何实施减振策略。还有一个重点是确定如何评估“临界速度”和“轨道临界速度”，目的是提供与瑞利波速相关的明确设计指南。为了帮助解决这个问题，常规的现场调查数据进行了审查，并与临界速度计算相关联。目的是为如何从现成的常规现场调查数据中预测临界速度提供新的思路。(C) 2014 Elsevier Ltd.版权所有。
This paper reviews, synthesises and benchmarks new understandings relating to railway vibrations. Firstly, the effect of vibrations on passenger comfort is evaluated, followed by its effect on track performance. Then ground-borne vibration is discussed along with its effect on the structural response of buildings near railway lines. There is discussion of the most suitable mathematical and numerical modelling strategies for railway vibration simulation, along with mitigation strategies. Regarding ground borne vibration, structural amplification is discussed and how vibration mitigation strategies can be implemented. There is also a focus on determining how 'critical velocity' and 'track critical velocity' are evaluated - with the aim of providing clear design guidelines related to Rayleigh wave velocity. To aid this, conventional site investigation data is reviewed and related to critical velocity calculations. The aim is to provide new thinking on how to predict critical velocity from readily available conventional site investigation data. (C) 2014 Elsevier Ltd. All rights reserved.
