中文摘要 | 國內既有橋梁長年維護不盡妥善,且近年來地震、颱風、豪雨等天然災害頻繁,使得橋梁之安全及劣化問題趨於嚴重,老舊橋梁修復補強問題已刻不容緩。經歷921大地震,橋梁耐震設計規範重新修訂後,目前既有橋梁之安全評估、拓建及改建工程,正逐步推展過程中,將面臨更多基礎如何修復補強之課題。本文嘗試藉由橋梁基礎修復補強的原因剖析,決策流程、工法選用與設計之探討,期能供作爾後基礎修補之參考。 |
英文摘要 | Some of Taiwan’s existing bridges have not been well maintained for years. In addition, frequent natural disasters such as earthquake, typhoon, and torrential rain have worsened the condition of the existing bridges seriously. The rehabilitation of old bridges has to be performed as soon as possible. After the revision of the Bridge Seismic Design Code after 921 earthquakes, the safety evaluation and rehabilitation of existing bridges have commenced step by step. The rehabilitation work will inevitably face the foundation retrofit problem. This paper aims to discuss the causes of bridge foundation retrofit, the decision making flowchart, and the selection of retrofit measures for later foundation retrofit design reference. |
