作为更可持续的交通选择，发展长距离和城市内的铁路网络是非常必要的。然而，噪音和振动被视为对环境的负面影响。与空气噪声相比，地面振动的相关问题要复杂得多。不同地点的地面性质差别很大。没有统一的评价标准或测量量，也没有与噪声图相对应的标准。地面振动被传送到建筑物内，并被视为可感知的全身振动或低频噪音；它也会影响敏感设备，但它的水平通常太低，不会对建筑物造成结构或外观损坏。综述了可感知振动和地面噪声的评价标准、经验和数值预测方法、影响振动水平的主要车辆和轨道参数以及一系列可能的缓解方法。
ABSTRACT There is a great need to develop rail networks over long distances and within cities as more sustainable transport options. However, noise and vibration are seen as a negative environmental consequence. Compared with airborne noise, the related problem of ground vibration is much more complex. The properties of the ground vary significantly from one location to another. There is no common assessment criterion or measurement quantity and no equivalent to the noise maps. Ground-borne vibration is transmitted into buildings and perceived either as feelable whole-body vibration or as low frequency noise; it can also affect sensitive equipment but it is generally at a level that is too low to cause structural or cosmetic damage to buildings. A review is given of evaluation criteria for both feelable vibration and ground-borne noise, empirical and numerical prediction methods, the main vehicle and track parameters that can affect the vibration levels and a range of possible mitigation methods.
