Abstract:	現今科技日益進步，製造技術亦趨於精密，振動問題顯然成為良率高低的重要一環。日前發展連接台北－高雄間的高速鐵路亦開始動工，其已規劃貫穿台南科學園區，在高速鐵路的貫穿下，南科的可用土地面積勢必減少，所以我們有必要在這股巨大能量的波傳振動問題上做一番評估及研究。本文將鋼軌假設為一無限長樑、土壤為一彈性基礎、高速列車則視為一移動載重，並使用脈衝函數來描述此移動載重，討論載重在不同的移動速度下，地表上不同量測點的振動情形，並探討在不同的載重大小等情況下，對地面振動的影響。 At present the technology progresses day by day, and the manufacture technique is more and more accurate. The vibrational problem obvious plays an important role on the yield of height. A few days ago, the high speed railway which connects Taipei to Kaohsiung has started to work. It has planned to pass through Tainan Science-based Industrial Park. The study assumes the rail as an infinite length beam, the soil as an elastic foundation, and the high speed railway as a moving load. We use Dirac delta function to describe the moving load, and discuss the vibration response on the different measurement point of the ground when the load on different moving velocity. And probe into the ground vibration on different load.
