非破壞性空間科學技術應用於橋梁檢測之研究

傳統的橋梁檢測，主要依賴土木工程人員進行目視檢測和非破壞檢測評估橋梁的狀態。本研究係以測量人員的角度出發，利用多元化空間科學的技術，運用非破壞檢測方式進行橋梁檢測工作。透過結合目視檢測、多星系衛星定位檢測、傾斜儀檢測和3D LiDAR光學掃描等技術，藉以檢測大溪橋和武嶺橋及其結構健康診斷。
本次研究之方向可大致歸納為以下：
1.傳統方式（目視）檢測橋梁。
2.多星系觀測系統進行控制點位測量。
3.傾斜儀實施振動檢測。
4.3DLiDAR儀器掃描並建立數位模型。
5.各式空間科學觀測資料數據比對。
6.整體橋梁健康檢測報告。
本研究的目標是運用這些先進的檢測技術，對橋梁進行全面的評估和分析。透過整合不同的檢測方法，我們預期可以獲得更多元且具有高度精確性的橋梁資料，並為橋梁的維護與管理提供重要的參考依據，進而確保用路人的安全。綜合本實驗之數據來做判定，兩座橋梁現階段（2023年）的健康診斷結果，大致結構部分皆為“健康”範圍。

Traditional bridge inspection rely primarily on civil engineering staff using visual inspection and non-destructive testing to assess the condition of bridges. This research is based on the surveyor's point of view, using diversified space science technology and Non-Destructive Testing(NDT) to execute the duty of bridge inspection.
By combining visual inspection, multi-satellite Positioning measurement, inclinometer testing and 3D LiDAR laser scanning and other technologies, the date is analysed for the structural-health-diagnosis of Daxi Bridge and Wuling Bridge.
The direction of this research can be summarized as follows:
1.Traditional (visual) inspection of bridges.
2.Multi-Satellite Positioning for control point measurement.
3.Inclinometer implemaitation for vibration testing.
4.3D LiDAR laser scanning and buildings a digital model.
5.Comparison of various space science observation data.
6.Overall bridge Structural-Health-Diagnosis report.
The study’s goal is to perform a comprehensive assessment and analysis of the bridge using these advanced inspection techniques. By integrating different testing methods, we expect to obtain more diverse and highly accurate bridge data and provide important references for bridge maintenance and management, thereby ensuring the safety of passers-by.
