捷運木柵線交通振動特性之研究

Abstract

本研究根據捷運木柵線之路線結構與列車運行特性分別在ぇ陳情點；え車 站；ぉ加速段；お定速段等地點，於捷運木柵線高架橋墩柱底端地面進行 捷運交通振動量測，進而分析木木柵之交通振動特性。又為瞭解捷運木柵 線沿線之道路振動型態，並且以此作為捷運交通與背景振動分離之依據， 因此，於捷運木柵線墩柱底端地面、道路與人行道接鄰兩處進行道路交通 振動之量測記錄。此外，本研究為瞭解捷運木柵線列車通過時導致建築物 內部振動之影響狀況，於陳情點附近選擇適當的地點進行建築物內部之振 動量測，進而瞭解捷運木柵線況線建築物之振動型態與影響程度。再根據 實測資料探討捷運交通與列車速率、列車承載量、列車加減速狀況與線形 等因素之關係，藉由統計學之多元線性迴歸方式構建捷運交通振動之預測 模式，進而提供捷運局作為日後木柵線捷運交通振動分析、防制與預測之 研究基礎與參考。 According to the characteristic of structure and the operation of the Mucha Lineof Rapid Transit, the paper measres the ground vibration at (1)the problem position; (2)station; (3)accelerative and decelerative section; (4)the constantvelocity section under the elevated bridge of Mucha Line to analyze the characteristic of vibration. In order to understand the type of the traffic vibration on the road and take it as the basis to separate the environment vibration from the vibration caused by train, the paper measures traffic vibration on the ground under the elevated bridge and roadside. To understand the effects in the building while train passing, the paper selects proper positions ing the building to measure the ground vibration around problem position to determine the type of the vibration via Mucha Line. By means of the measurement, the paper researches the relationship between theground vibration from passing train, train speed, the passengers of train, acceleration, deceleration and the shape of line etc. Therefore, the paper tryto take advantage of the analysis of regression to establishes a ground vibraiton prediction model to offer the Company of Rapid Transit as a basis andreference in the analysis, control, and prediction of vibration for the train of the Mucha line of rapid transit.
