中文摘要 | 0206美濃地震造成台86線24號橋損壞,預力混凝土箱形梁之盤式支承位移,原本緊密的東西向橋面因而錯開,最大出現約60公分間距,長度達250公尺,危及橋梁安全。公路總局第五區養護工程處,立即以型鋼組立臨時支撐來強化結構安全,封閉東行線但保留西行線通行。並依序進行橋梁震損調查、橋梁地震特別檢測與安全評估、橋梁耐震評估及補強。並進行為期兩年之橋梁長期安全監測,以掌握補強後之橋梁安全狀況。本文整理之結論與建議,可提供未來橋梁受震害之處理程序與因應對策,並成為建立橋梁管理參數(警戒值、行動值)之重要參考。 |
英文摘要 | The Meinong Earthquake in Southern Taiwan on February 6, 2016, resulted in damage to Bridge No. 24 of Provincial Highway 86. The seismic damage was as follows: residual lateral displacement was about 60 cm of the beam, severe damage of the bearing, shear micro-cracks on the surface of the bridge pier, external micro-cracks on the box girders, and longitudinal micro-cracks on the internal roof plate of the box girder. The damage condition endangered the bridge safety. After emergency responses from the Fifth Maintenance Office of the Directorate General of Highways, repair and retrofit design by CECI Engineering Consultants, construction work by a general constructor, and evaluation and vehicle load tests by the National Center for Research on Earthquake Engineering (NCREE), the bridge was reopened to traffic on May 20, 2016. This study briefly describes the bridge seismic evaluation and retrofit process, as well as the post-earthquake investigations, vehicle load tests, and long-term monitoring by the NCREE. |
