中文摘要 | 都會區捷運、鐵公路及維生線工程為提昇都市生活機能之重要建設,惟因都市人 口密集化、用地取得不,易工程規劃上須積極利用地下空間,因此,為因應都會區特殊施工 條件及地層特性之隧道施工技術日益重要。都會區隧道工程特性主要為淺覆蓋、地下水及地層 軟弱所衍生之施工問題, 以及地表沉陷、噪音及震動所衍生之環境問題,NATM 工法在此種 設計條件上之適用難度較高、且經驗較少,但為追求工程之經濟性及合理性,仍有其存在之 必要。本文旨在探討 NATM 應用於都會區軟弱地層隧道之適用性,並探討其設計及施工方式 ,對於我國都會區捷運工程隧道之規劃提供一個新的審思的方向。 |
英文摘要 | MRT,railway, highway and lifelines are all very important to promote the living standard at Taipei metropolitan area. However the very dense population and land acquistion problem require active use of the underground space. Therefore, the tunnelling in difficult construction condition and soft ground at metropolitan area is unavoidable so that construction technique of tunnel becomes more and more important. Tunnel at metropolitan area may meet construction difficulties, such as shallow overburden, underground water and soft ground. Also, it amy encounter environmental impacts, such as ground subsidence, unpleasant noise and vibration. Though the adaptability and experience of NATM utilised in the said circumstance is limited, however, in consideration of the condition for low cost and appropriateness, NATM is still needed. This paper aims to discuss the adaptability of NATM utilised in soft ground at Taipei metropolitan area. Also, the design and construction of NATM is included. It is expected that the experience derived from this paper would be helpful in gaining further insight into the planning of NATM at metropolitan area so that more effective design and techniques can be developed for such problem. |
