本文介绍了一个理论地面振动模型和三个站点的实测数据之间的比较。该模型，这是简要概述了这里，包括准静态和动态机制的激励。在无限长轨道上以恒定速度行驶的车辆的垂直动力学耦合到三维分层地面的半解析模型。该模型还用于演示不同频率下的两个振动分量以及列车速度低于和高于最低地面波速度时的作用。研究发现，在大多数实际情况下，动态分量引起更高水平的振动。(C)2003 Elsevier Ltd.保留所有权利。
This paper presents comparisons between a theoretical ground vibration model and measured data at three sites. The model, which is briefly outlined here, encompasses both the quasi-static and dynamic mechanisms of excitation. The vertical dynamics of a number of vehicles travelling at a constant speed on an infinite track are coupled to a semi-analytical model for a three-dimensional layered ground. This model is also used to demonstrate the roles of the two components of vibration at different frequencies and for train speeds below and above the lowest ground wave speed. It is found that, in most practical cases, the dynamic component gives rise to the higher level of vibration. (C) 2003 Elsevier Ltd. All rights reserved.
