中文摘要 |
自有地震儀觀測90年間以來,臺灣地區已發生多次重大的地震災害。88年9月21日發生芮氏地震規模達7.3的921集集大地震,造成臺灣相當重大的生命及財產損失,使人不得不懾於大自然無與倫比的力量。此次地震後橋梁結構物之耐震安全成為國家防災計畫非常重要的課題,而國道高速公路為臺灣地區南北交通的大動脈,對於國家整體經濟發展及民生影響甚鉅。臺灣區國道高速公路局為防範於未然,開始分階段持續推動高速公路橋梁耐震評估補強工作。在耐震補強工法中,橋柱包覆補強可有效提升橋梁於強震時之韌性,國內橋梁耐震補強工程常見之包覆補強方式為鋼筋混凝土包覆及鋼板包覆補強工法。鑑於補強材料科技日新月益,碳纖維材料其具有承受主要負載、限制微裂紋延伸、提高材料強度與剛性、改善材料抗疲勞、抗潛變性能及提高材料使用壽命之特性,因此高公局於「國道橋梁耐震強工程」中考量若因空間受限、美觀要求或施工條件不適用混凝土及鋼板包覆工法時,採用纖維強化高分子複合材料包覆工法(FRP包覆),藉由碳纖維材料重量輕、強度高、易施工等的特性以提高高速公路橋梁的耐震能力與累積本土之設計、施工及檢測維護經驗,期能提供國內橋梁未來耐震補強更多的工法選擇。 |
英文摘要 |
Chi-Chi earthquake measuring 7.3 on the Richter scale struck Taiwan on September 21, 1999, and caused severe property losses and casualties to central Taiwan. After the earthquake, the seismic safety of the bridge structure has become a very important issue in the national disaster prevention plan. The national freeway is the main traffic artery connecting the north and south in Taiwan, which has great influence on the national economic development and the people's livelihood. Taiwan Area National Freeway Bureau (TANFB) actively took preventive measures for the bridge structures. The bridge columns jacketing can effectively increase the flexural ductility and shear strength of the bridge in large earthquake. The reinforced concrete jacketing and steel jacketing are the most widely used in the domestic bridge columns seismic retrofit project. In view of the ever-changing materials technology, carbon fiber material has the characteristics of bearing the load, limiting the micro-crack extension, improving the material strength and rigidity. The material can also improve the material anti-fatigue, anti-creep performance and service life. When the space is limited, the landscape requirements or construction conditions are not applicable reinforced concrete jacketing and Steel Jacketing , the seismic retrofit program of national freeway bridges using carbon fiber reinforced polymer composite jacketing (CFRP jacketing). With carbon fiber materials' light weight, high strength, easy constructed and other characteristics, increase the seismic capacity of freeway bridges, and accumulate the experience of domestic design, construction, testing and maintenance. Looking forward to provide more choice for future domestic bridge seismic retrofit project. |
