中文摘要 | 極端氣候極造成颱風、暴雨、土石流等天災,對橋梁安全造成極大之威脅。「臺灣地區橋梁管理資訊系統」目前正常使用之橋梁共有兩萬八千餘座,但過去並未留存歷史橋梁受災資料,因而無法探討災因或減少遭受類似災害之威脅。有鑑於此,本研究建立災損橋梁資料庫系統,以供橋梁管理人員維護橋梁參考。此資料庫系統可針對某一災害所造成之損壞橋梁,輸入災害資訊、災損橋址之現地資料,並可進行災前災後橋梁基本資料與相片等資訊之比對,亦可提供各種災害與災損橋梁之統計資訊。本研究完成之災損橋梁資料庫已蒐集賀伯颱風、九二一大地震、桃芝颱風、敏督利颱風、莫拉克颱風以及蘇力颱風等共205座災損橋梁之資料,並已整併至「臺灣地區橋梁管理資訊系統」上線使用,藉此保存災損橋梁之災情資訊與當時之周遭環境情況,以利於後續橋梁分析災損原因,並提供橋梁管理機關於重建與維護其他橋梁時之參考。 |
英文摘要 | Many natural disasters such as typhoons, torrential rainfalls, and debris flows are serious threats to the safety of bridges and are usually worsened by extreme weather conditions. Currently there are more than 28,000 bridges in the "Taiwan Bridge Management System (TBMS)." However, there was no historical data stored for bridges damaged or destroyed by those natural disasters. This research aims at establishing such a system which focuses on building an inventory database for the bridges which were damaged by the various natural disasters in Taiwan. In addition to the inventory for damaged bridges, the system is able to store information of the disaster, possible factors which might relate to the damage, such as water levels and rainfalls, and the conditions of damages. 205 disaster-damaged bridges from the 921 earthquakes and several pat and recent typhoons, including the notorious typhoon Morakot which caused serious damages to 129 bridges, have been input into the system to serve as part of the functions of TBMS. The established system should be very helpful for the bridge management agencies to take precaution measures for disaster prevention related to maintenance of bridges. |
