摘要

台南科學園區內之高科技廠房與設備，在其生產製程中對振動相當敏感，易受樓版之振動所影響。因此本研究旨在針對園區內可能對高科技廠房產生振動影響之行車振動源進行量測，包含高鐵列車與重型貨車行駛通過時所引致之振動，分別就兩者對地盤所產生之振動，進行地盤振動特性與衰減特性之分析，並就分析結果進行相互之比較，討論在相同地盤條件下，不同型式振動源所引致地表振動特性之差異，以探討其可能對園區內高科技廠房之影響。

The high-tech fabs and equipments inside the Tainan Science Park (TSP) are very sensitive to vibrations during the process of production. Therefore, in-situ measurements for the ground vibrations induced by moving vehicles were conducted at the site of Tainan Science Park in this study. The measurements conducted include the ground vibrations induced by the Taiwan High Speed Rail (THSR) trains and heavy trucks. The characteristics of the ground vibration excited by these two different sources, such as the amplitude, the spectral content, and the attenuation coefficient, were analyzed and compared to show the differences in the ground vibrations induced by different vibration sources at the same site. In addition, possible influences of these vehicle-induced vibrations on the high-tech fabs in TSP were discussed.
