隨著臺灣高科技業的進步，先進製程的精密程度也日漸提高，因此微振對製程的影響已經不可忽視。此論文研究高鐵台南站造成的振動對高科技廠房的影響，首先到現地使用加速度計蒐集多點的數據，透過數據整理得到速度跟微振的關係。運用整理之數據建造一與現地結果相近之有限元素模型，此模型是涵蓋了高鐵、土壤、結構物的完整模型，在確定模型可靠性後，將針對模型的基礎設計做改變，減小地下室微振動，並且透過模擬結果預測未來結構興建完成後，高鐵行車振動在各種車速對結構產生之影響及共振現象。
實驗與有限元素分析結果顯示高鐵車速在時速260-270公里時會與橋墩x方向產生共振，對680m外之素地造成超過VC-E標準的微振，另外高鐵在時速205-220公里時產生的振動會跟數值模擬之高科技建築結構發生共振，因此若是高鐵能調整速度，建議將速度定在時速240公里或是200公里以下最為保守。若高鐵無法調降車速，在此篇論文中也有提供多種從基礎結構改變降低振動的被動控制方法，其中最有效的方法為加大基礎底板尺寸，放大底板不只能有有效應對微振低頻波波長較長的現象，若底板尺寸夠大也可以將地震振動影響降低至少一半，但此方法受限於腹地較大的科技廠房，可以把不同廠區的基礎底板連接達到放大底板的效果。
論文中所有降低微振的方法中，降低車速的效益最高，因為此方案不僅無需額外的工程成本，在2.5公里內將高鐵車速從時速270公里降至240公里僅會增加3.6秒的行駛時間，將高鐵車速從時速270公里降至200公里也僅會增加11秒的行駛時間，不只時間影響極小，也能讓直達車在經過過車站時，降低振動，提高旅客舒適度。然而，對於位在地震帶的科技廠房，仍建議採取基礎底板放大的方法，以同時減少微振與地震對先進製程的影響，提高生產穩定性與產品良率。

With the advancement of Taiwan's high-tech industry, the precision of advanced manufacturing processes has been continuously improving, making the impact of micro-vibrations on these processes increasingly significant. This study investigates the vibration effects caused by the Taiwan High-Speed Rail (HSR) at Tainan Station on high-tech factory buildings. Initially, accelerometers were used on-site to collect multi-point vibration data, which were then analyzed to establish the relationship between train speed and micro-vibrations. Based on the processed data, a finite element model (FEM) was constructed to closely match real-world observations. This model incorporates the HSR, soil, and structural elements to ensure a comprehensive analysis. After verifying the reliability of the model, modifications were made to the foundation design to mitigate micro-vibrations in the basement. Additionally, simulations were conducted to predict the effects of train-induced vibrations at various speeds and the occurrence of resonance once the structure is fully constructed.
The experimental and finite element analysis results show that when the high-speed rail operates at a speed of 260-270 km/h, it induces resonance in the x-direction of the bridge pier, causing micro-vibrations exceeding the VC-E standard at a bare ground location 680 meters away. Furthermore, vibrations generated at train speeds of 205–220 km/h resonate with the simulated high-tech building structure. To minimize these effects, it is recommended that, if possible, HSR train speeds be adjusted to either 240 km/h or below 200 km/h for a more conservative approach. If speed reduction is not feasible, this study also explores various passive vibration control methods that modify the foundation structure to reduce vibrations. Among these methods, increasing the foundation slab size proves to be the most effective. A larger slab not only effectively counteracts long-wavelength, low-frequency micro-vibrations but also reduces seismic vibration effects by at least 50% if the slab size is sufficiently large. However, this approach is more applicable to high-tech factories with larger land areas, where interconnecting the foundation slabs of different factory zones can achieve similar benefits.
Among all the vibration mitigation strategies discussed in this study, reducing train speed is the most efficient solution. This approach requires no additional construction costs and has minimal impact on travel time. Lowering the train speed from 270 km/h to 240 km/h over a 2.5 km distance would only increase travel time by 3.6 seconds, while reducing it further to 200 km/h would extend travel time by just 11 seconds. This minor adjustment not only minimizes the impact of micro-vibrations but also enhances passenger comfort when express trains pass through stations. However, for high-tech factories located in seismic zones, increasing the foundation slab size is still recommended as it effectively mitigates both micro-vibrations and seismic effects, thereby improving production stability and product yield rates.
