This paper studies the characteristics of ground vibrations due to underground trains and their transmission laws.The study consists of the simulations of the train-track system vibration,which provides the excitation loads of moving trains onto the tunnel structure,and the calculation of the track tunnel-ground system vibration,by which the transmitting properties of ground acceleration and velocities are studied.The main results include 2 aopectcs:vibration amplifying area exists certain distance away...

This paper studies the characteristics of ground vibrations due to underground trains and their transmission laws.The study consists of the simulations of the train-track system vibration,which provides the excitation loads of moving trains onto the tunnel structure,and the calculation of the track tunnel-ground system vibration,by which the transmitting properties of ground acceleration and velocities are studied.The main results include 2 aopectcs:vibration amplifying area exists certain distance away from the tunnel centre,and thedominant frequencies of the ground vibration concentrate to a certain band.Buildings that locate in that area and whose resonance frequency drops into that frequency band would be greatly influenced by the underground train-induced vibration.

本文的研究包括两部分:(1)轨道基础──衬砌结构──地层系统的响应模型,以分析列车振动荷载的传播规律;(2)地铁车辆──轨道系统的振动模拟,以确定列车振动荷载。主要结论是:(1)离开地铁隧道中心线一定距离的地表范围内,存在一个振动放大区;(2)存在一个地层响应的主要频带,在此范围以内的地面建筑如果其自振周期落于这一频带,则会受到过往地铁车辆振动的显著影响。

This paper describes briefly features of underground driving command, then gives the system functions in accordance with the features. Finally, the paper discusses wireless communication system scheme for underground train to satisfy the system functions.

文章首先简介地铁行车指挥的特点,然后提出符合这种特点的系统功能,最后论述一个满足系统功能的地铁列车无线通信系统方案。

The paper introduces the PSD system used by the underground train in Guangzhou, mainly about the consisting parts and the function of its mechanical and electrical part.

文章较详细地介绍了广州地铁使用的屏蔽门系统,重点是它的机械和电气部分的组成和作用.
