臺北捷運系統營運後，部份隧道路線段上方居民對振動噪音污染有抱怨與不滿，為減輕 軌道噪音與振動所造成之影響，臺北捷運新蘆線軌道工程首開先河，引進國外已有三十多年 實績，目前世界上公認在軌道工程方面最具有減少振動、抑制噪音效益之浮動式道床軌道 (Floating Slab Track)，以解決振動及其二次噪音污染問題。浮動式道床軌道於國外係屬成熟 的技術，也發展出多種不同的設計，但是因為世界上專精於浮動式軌道設計的顧問很少，有 經驗的施工廠商更不多，雖然各系統之間有其相似性可加以參考，但因地理環境不一樣，且 契約型態及要求也不同，所以執行時也不能完全移植國外那一套至本地，尤其浮動式道床軌 道是全國首創首次採用，眾所矚目，實在不容許有任何差錯，故相關施工之規劃、流程、步 驟、時效與品質等各方面制度之建立與落實，將影響浮動式道床軌道之施作成效。 本文乃針對這全台首創的浮動式道床示範段之施工加以完整紀錄，供大家參考。

After Taipei MRT began commercial service, relevant authorities have received complaints from residents living in the vicinity where MRT system passes beneath. With a view to mitigating the impacts of noise and vibration caused by the system, Taipei MRT Xinzhuang-Luzhou line takes the lead in adopting an overseas technology, Floating Slab Track (FST), which has been applied in many railway construction projects around the world for more than 30 years.FST is a wellrecognized infrastructure trackwork technology that efficiently reduces ground borne vibration and noise. It also helps terminate pollution problems such as vibration and secondary noise. Floating Slab Track is a well-developed technology with an extensive design history in many foreign countries; however only limited information is available for reference with few specialist consultants and experienced constructors. The adoption of the FST system on MRT lines requires slight modifications due to geological constraints and the nature of the contract. As it is the first time that FST is applied in MRT construction in Taiwan, great attention is being paid to the setting up of an optimal system and the implementation of high quality construction planning, sequencing, procedures in order to create effectiveness that will lead to successful FST performance. This paper aims to keep a complete record of the FST construction, the first ever in the nation, for readers’ reference.
