高速列車通過引起之地表振動，必須設法降低至精密電子業能容忍的程度，因理論分析未能掌控各種實際情況，故須輔以實驗觀察，一方面供分析模型之參考和驗證;另可了解振動衰減特性。本論文研究目的為探討隔振牆與振波阻隔板對降低南科地區振波傳遞振幅之可行性以及相關限制條件。先進行小規模振動機實驗，搜集相關資料，驗證理論分析準確性與校正相關參數，建立合理之數值模型，以此可靠之數值模型分析隔減振措施的效果，以發掘問題及瞭解隔振對策之有效性與相關限制，提供工程單位之應用參考。 In the present study, the field tests of the ground vibration induced by a vibrator and the reduction of vibrations from the isolating system will be carried out. In this study, The experiments data collected will be used in the revisions of the theoretical models. The numerical model will be correctly designed based on the shaker test. Use this analysis to find out the effectiveness and constrained conditions of the vibration isolating system such as trench and block will be examined.
