中文摘要 | 日本目前有許多尚待進行之水中橋墩耐震補強工程,而由於對水中橋墩進行補強工程時,其圍堰與抽水作業之成本比例大,因而使得降低成本為水中橋墩補強之一重要課題。PRISM工法用於水中橋墩耐震補強時,不需進行圍水作業,而是將內含補強鋼材之預鑄面版包覆於既有橋墩周圍,其與既有橋墩間之縫隙原則上以灌漿填充方式處理。關於PRISM工法之主要材料,宜掌握能提升施工性與品質之規格以及方案,預鑄面版之組裝、設置方法,精度控管與精度確保等方法之一系列的施工方法,都經由位於沿海之水中橋墩之實際工程而被確立了。此外,藉此也能掌握補強工法之整體工程、循環工程、工程費用,而PRISM工法相較於傳統工法之優異性也得到驗證。 |
英文摘要 | A seismic retrofit method, PRISM method, for piers in water without expensive dry-up process is introduced in the paper. Pre-cast panels, including reinforcement steel plates, are used to surround the piers for retrofitting. Subsequently, mortar is used to fill the gap between the pier and the panels. Experiences gained after some applications prove the workability and quality of the PRISM method. One application is also introduced in the paper to verify the superiority of the construction process and the low construction cost, comparing to other retrofitting methods. |
