    Abstract: 橋梁之管理維護已成為臺灣社會及經濟層面關注的議題,尤其對於災後受損橋梁

    (Analytic Hierarchy Process, AHP)取得各參數之權重,以建立優選排序之模式。

    管理關用於路網層級之橋梁優選排序,並可應用於橋梁管理系統中。;Management of existing bridge infrastructure has become a major social and economic concern in Taiwan. This is due to the critical conditions of bridges driven by post-disaster deterioration and the controlled funds available to timely repair their deficiencies. However, reliable assessment of a bridge’s structural health is important to predict the progress of deterioration, to provide the required inputs for making cost-effective MR&R decisions; and to ensure that safety, serviceability, and functionality of a bridge can be sustained over its designed service life. In this regard, a model for prioritizing damage inspection of bridges for MR&R activities after natural disasters is necessary.

    This thesis presents the development of a model, which proposes a method to facilitate post-disaster prioritization of bridges by virtue of their structural vulnerability and strategic importance to implement inspection and rehabilitation operations. To achieve this objective, this research combined literature and feedback from industry professionals through interviews as primary sources of data. The proposed model adapts an Analytic Hierarchy Process (AHP) technique. The research findings have identified decision objectives and parameters essential to rank bridge rehabilitation projects, and these are included within a framework to prioritize bridges while incorporating experts’ input in the process.

    The developed model is a flexible framework, which is applicable to a variety of disaster events and other conditions causing abrupt damages to transport infrastructure where decisions on maintenance strategies must be made promptly. Specifically, it provides the decision-maker with a simplified and systematic approach to assess bridges by addressing the critical parameters of safety and cost-benefit in prioritizing funds and work allocation. The proposed model can be used by departments of transportation to rank bridges in a network, and it can be integrated within an existing bridge management system.
