摘要

臺灣長年雨量豐沛，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等影響。本研究將持續以臺鐵大甲溪橋即時監測系統為研究背景，對建置後系統監測的歷史事件整理，針對可能造成影響的因素與相關技術，提出改善方法與對策。
本研究將回顧已建置完成並實行之鐵路橋墩柱即時監測系統的歷史成果與管理方法，並對系統本身可能受到的如環境、溫度、螺帽鬆動等各種外界不確定之影響因素，提出其改善方法與對策，例如以綠水泥包覆儀器固定座來杜絕溫度效應等，將以此為方向做逐一的探討與研究。
鐵路橋梁即時警示通報系統是以提供即時 (Real Time)且正確的警示通報，如何將系統各項影響因素排除並提供最正確且有效、簡單的管理機制是重要的，以此方能達到有效避災、防災、減災的成效。

Bridge has been an important transport hub. In particular, railway bridges across rivers often tilt due to erosion and flood caused by heavy rain or typhoon. Previous studies have discussed bridge structural damage by tunneling or the resulting road safety issues. Nevertheless, in the previously constructed research background, the summary of historical events of system monitoring demonstrated that false alarming of the disaster prevention and mitigation warning system, if provided, will generate a great impact on administrative and relevant units.
Therefore, this study summarized and reviewed special events of the past, the real time data and solutions to explore possible influence factors of uncertainty that the system may be subject to, including environment, temperature and loosening of nuts. Based on the results, it proposed more perfect improvement methods and strategies such as the elimination of temperature effect by using concepts group -coated equipment bracket. Meanwhile, for effective verification and comparison, this study conducted in the laboratory a series simulation tests for comparison to fully present differences in monitoring data before and after improvement. Finally, this study conducted one-by-one analysis to explore and do research on related issues.
The Railway Bridge Real Time Warning System can provide real time and accurate warnings. Reducing or eliminating various influence factors of the system and provide the most accurate, effective and simple management mechanism are important to achieve disaster prevention and mitigation.
