中文摘要 | 大臺北都會區人口密集大樓林立且交通繁忙,大眾捷運系統建設的推展確實為民 眾帶來極大的方便,惟為減少對整體環境之衝擊,多採用地下結構系統,因此站體區 之深開挖工程即成為施工重點,尤其於系統交會處,更有其超深開挖之需求。本文以 新北市政府推動捷運「三環三線」中第三環之主要部分:臺灣桃園國際機場聯外捷運 系統計畫,位於大臺北都會區中心-臺北車站特定專用區內之端點站也是臺北市唯一 車站-臺北站為例,介紹都會區內之大面積深開挖工程之設計、施工及管理。 台北站做為機場捷運之端點站,除了將國家門戶延伸至首都外,地面上將聳立 兩棟高56層及76層之共構聯合開發大樓,具有提升臺北西區都市發展及國家形象之 功能,大樓基地呈長梯型,東西向約350公尺,平均寬約80公尺,橫貫台北車站西側 C1、D1用地及重慶北路,面積2.8公頃,約4個足球場大,地下共設計四層,開挖27.1 公尺深,總土方開挖量逾80萬立方公尺,可為大區域深開挖工程之代表案例。 |
英文摘要 | For a city like Taipei with heavy traffic and a high density of high-rise buildings, the development of the MRT system has brought great convenience to residents. In order to minimize the impact on the overall environment, most Taipei MRT routes were constructed underground. As a result, deep excavation at the stations has become a key part of system construction with especially deep excavation needed for the transfer stations. This paper aims to conduct a case study of Taipei Main Station in Taipei Main Station District and introduce the design, construction, and management of a large-area excavation. As a terminal station of the line that will connect the city to Taoyuan International Airport, Taipei Main Station not only extends the nation's main gateway beyond Taipei, the capital of Taiwan, but also bears the function of boosting urban development in western Taipei. Meanwhile, the national image will be highlighted with the 56-story and 76-story jointdevelopment buildings. The trapezoid-shaped site, situated on Chongqing North Road and Taipei Main Station District Parcel C1/D1 west of Taipei Main Station, will be about 350 meters long from east to west with an average width of 80 meters. In total, it covers 2.8 hectares, equal to some four soccer fields. The excavation is 27.1 meters deep with total earth excavation of 800,000 cubic meters, making it a representative example of large-area excavation. |
