鐵路橋梁實時警示通報監測系統創新與建置研究
Innovation and Establishment Studies on the Real-time Safety Caution-Notifying of the Monitoring System for Railroad Bridge
摘要
摘 要 關鍵詞：實時、監測、鐵路橋梁、管理值、橫向水平位移 台灣河川多屬坡陡流急，在豪雨或颱風挾帶之洪流衝擊下，常造成鐵、公路橋梁橋墩基礎遭受沖刷而產生傾斜、淘空造成橋梁結構受損或行車的安全的影響。橋梁以用途區分為公路橋梁與鐵路橋梁，本研究將以台鐵大甲溪橋為背景，建置鐵路橋梁實時警示通報監測系統並提出其創新及優勢。 本研究將採用表徵式監測方法，其中橋墩之傾度變化能反應落橋或出軌前之徵兆或變異徵兆，採用適用於鐵路軌道的管理值：橫向水平位移，控制列車脫軌的安全性；軸向水平位移，控制橋梁結構的落橋行為。 鐵路橋梁實時警示通報系統提供即時、實時(Real-Time)的警示通報；雙向控制的管理值提供有效、簡單的管理機制。形成有效避災、防災、減災的成效。

Abstract Key words：real-time、monitoring、railroad bridge、management value、Transverse horizontal displacement Most rivers and creeks in Taiwan are rapids; with torrents of rain brought by Typhoon and cloudburst, the rapids strike and wear the base of railway, highway and bridge, resulting in steep and empty foundations, the damage of bridge structure, and the effect of driving safety. Bridges were divided by purpose into two categories, highway bridge and track bridge. This research takes Dajiaxi railroad bridge as background to establish the Real Time Automatic Monitoring System and address its innovation and advantage. This study applies representative monitoring method, which can show signs or variations before bridge collapse or derailment according to the variety of inclination of bridge pier, and adopts management value that is applicable to railway track - - Transverse horizontal displacement, which can maintain the safety of derailment; axial horizontal displacement, which can control collapse behavior of bridge structure. The Real Time Automatic Monitoring System provides immediate and Real-Time alarms; two-way management value supplies effective and simple management mechanisms. To make use of above methods can effectively achieve the goal of avoiding, preventing and minimizing hazards.
