This study aimed first at revealing the vibration transmission mechanism from the train to nearby ground, and then at developing effective vibration counter measure called honeycomb WIB with tire fill-in based on the former knowledge. The following works have been conducted. :(1) Development of the computer simulation system for predicting the vibrations induced by train and trafficThe dynamic analysis for a track and ground system is investigated with due consideration of the moving load effect. The 2.5 dimensional solution method is taken for the effective and efficient procedure. The fundamental design formula of a honeycomb wave impeding barrier (WIB) is developed based on the knowledge of the wave field.(2) Field measurementsFrom the vibration measurement along a train track, the vibration transmission from train track through the ground was observed. The theoretical interpretation is made based on the data. The structural borne vibration and the ground borne vibration are then detected in comparison with the structural natural frequencies and the wave dispersion characteristic of the ground at site.(3) Field experimentThe dynamics of the tire fill-in WIB are investigated by the impact loading and harmonic loading. The vibration reduction of this measure is evaluated when it is constructed in the vicinity of a pile foundation. The results are also compared with the computer simulation.

本研究的目的首先是揭示从火车到附近地面的振动传递机制，然后根据现有知识开发有效的振动对策，称为蜂窝WIB和轮胎填充。已开展了以下工作。 ：（1）开发用于预测火车和交通引起的振动的计算机模拟系统研究了轨道和地面系统的动态分析，并适当考虑了移动载荷效应。采用2.5维求解方法是为了有效且高效的过程。基于波场知识，提出了蜂窝状波阻屏障(WIB)的基本设计公式。(2)现场测量通过沿火车轨道的振动测量，观察了火车轨道通过地面的振动传播。理论解释是根据数据做出的。然后与结构固有频率和现场地面的波频散特性进行比较，检测结构振动和地面振动。(3)现场实验通过冲击载荷和振动载荷对轮胎填充WIB的动力学进行研究。谐波负载。当该措施建在桩基础附近时，评估该措施的减振效果。结果还与计算机模拟进行了比较。
