| 中文摘要 | 本研究係利用既有鐵路橋梁上之地震力分散裝置為案例,對其進行現場檢測,判讀檢測結果評估其健康度狀 況。地震力分散裝置主要功能為在受低速載重狀態下僅提供輕微阻力,而在動態載重下,可瞬間提供額定設計力 以鎖定兩端結構,其對橋梁結構力學系統之影響不容忽視,目前並無明確規範現場檢測項目及標準,因此本研究 將針對地震力分散裝置進行檢測評估,確認其功能狀況,確保橋梁結構之安全性。 首先參照橋梁檢測常用之 D.E.R.U. 方法作為本案例目視檢測之方法,並擬定適用於地震力分散裝置檢測 項目,包含地震力分散裝置本體及鋼板托架兩大部分,針對各式異常項目進行檢查,同時量測插銷中心之距離 (pin-pin)作為評估項目之一,研擬出檢測表並拍照記錄。若發現疑似漏油情形,則進行採集並送實驗室分析, 確認油漬之化性。一般而言,外部油污可能是本體漏油或是沾染到之潤滑油,惟其化學成分迥異,藉此可進一步 確認漏油的可能性。現階段建立系統化初步安全檢測評估之作業方法,未來考慮納入智慧輔助系統,以利結構全 生命週期之管理。 |
| 英文摘要 | This study utilizes existing Lock-up Device (LUD) on railway bridges as case studies, focuses on inspections and structural health evaluation for devices. LUDs or STUs (Shock Transmission Units) connect girders and piers to provide additional strength to resist seismic forces on bridges. This system temporarily “lock” super-structure and sub-structure of bridge under earthquakes, or other fast-acting loads, while permitting slow movements such as thermal expansion and contraction. Currently, there are no specific standards, guidelines, or criteria for visual inspection items. Therefore, this study aims to evaluate LUD performance to verify its functionality and ensure the safety of bridges The D.E.R.U. method is widely used in visual inspection, and it is also the most common approach for the bridge inspection. Take the method as a reference, standard inspection forms for LUD are created that include checklist for anomalies, measurement of the pin-to-pin distance, and photographic documentation. Inspection items or checklist includes cylinder, bracket, fixture, and bolt. If any leakage of hydraulic oil is found, samples are collected and analyzed to the basic characteristics of a substance. A systematic preliminary safety inspection procedure is established in this study, and if conditions allow, new techniques, such as intelligent monitoring, real-time image recognition, can be utilized, the safety inspection procedure can be more accurate in the future. |
