摘要

高鐵行車引致之振動近年來引起工程師之研究興趣，一則希望瞭解其引致地盤之振動特性與大小，另則藉瞭解其特性以研究振動防治之對策。本文介紹目前世界上採用之四種高鐵系統之主要振動特性，並蒐集一些目前國外常使用之數種地工減振技術工法，探討其減振效果及其適用性，提供將來工程應用之參考。

The ground vibrations induced by high-speed train have drawn engineer's interest in recent years. The engineers need to study the vibration characteristics, which include frequency contents and vibration level, to find the vibration mitigation measures. This paper introduces the characteristics of ground vibrations induced by four high speed train systems, and reviews many approaches that have been suggested to be used for ground vibration mitigations. The effectiveness and applications of these vibration reduction methods are also discussed.
