中文摘要 | 捷運高架橋梁材料及型式之選定,主要考量因素包括以制式化施工方式縮短工 期,並須兼具美學及功能性、橋梁耐震能力、交通衝擊、施工條件、工期及經濟考 量、結構工程技術提昇、噪音及振動防制等因素整體考量。隨著橋梁工程技術發展日 新月異以及民眾生活品質不斷提昇,橋梁設計不僅是交通連結功用,更是生活中之藝 術產品,捷運系統亦需配合新技術、新工法的發展應用,使高架橋梁系統達到跨距長 大化、結構輕量化、施工自動化的高效率目標。 臺北捷運環狀線系統制式橋梁設計規畫採用跨距25公尺預鑄預力混凝土U型梁, 於特殊路段之非制式橋將因應地域環境條件,審慎評估選用之橋型系統,期使結構型 式能與週遭環境相互融合,藉以塑造嶄新的捷運新文化。 |
英文摘要 | The selection of material and style of an MRT viaduct structure is mainly based on the use of standardized construction methods to shorten the work period. Others major concerns include aesthetics, functionality, seismic resistance of the viaduct structure, impact on traffic, construction conditions, economic considerations, enhancement of structural technology, and control of noise and vibration. With the growing development of viaduct structure construction and improvements in quality of life, a viaduct is designed to not just be a transportation link, it is also an art-oriented product of life. Furthermore, MRT viaduct structures are also expected to be developed with the application of advanced technology and newest construction methods to meet the goal of high effi ciency, that is, longer spans, lightweight structures, and automated construction. During planning and design, it was decided that prestressed precast U-shaped girders with a 25 m wide span would be adopted as the standardized viaduct for the Circular line. As for the non-standardized viaducts on some special sections, in line with local environment conditions, careful assessment needs to be given to the selection of viaduct system to ensure that its structure is integrated with the surrounding environment, and to help create a new MRT culture. |
