摘要

本研究經藉由蒐集、彙整其他工區曾因支撐架組搭、拆除施作而發生工安、倒塌職災案例回顧資料可得知，係因未確實依設計圖、說、規範及支撐架組、拆安衛標準作業程序施作、且未確實落實每日勤前教育訓練、宣導機制及危害告知義務、亦未確實落實指派作業主管在場指揮、監督各項作業如：1.工區遭遇地震四級以上，需指派作業主管在場檢測、會勘支撐架位移、傾斜變形…等現象並記錄之2.混凝土澆置時，亦需指派作業主管在場指揮、監督各項澆置作業，以避免因澆置速度過快或澆置順序不當，使支撐架發生倒（崩）塌工安職災事件等。透過本研究研擬具體災害防範改善對策，以提供相關橋樑工程設施安全維護建議與意見，期能提升橋樑支撐架施工品質與安全，有效防範橋樑支撐架作業工安、職災之發生率，俾能達到「零災害」與「零工安」之境界與目標。

The research was conducted to study the safety facility management for bridge construction using cast-in-situ span by span method. A total of 3 bridge construction projects in the central Taiwan region were selected to provide typical field facility safety data during design, installation, and dismantle stages of the span by span bridge construction techniques. In the study, the practical project data were collected, analyzed, and discussed to reveal that facility safety failures were contributed to lack of drawing interpretation and specification of facility safety operation, and inadequate implementation of the required safety reinforcement conducts during each standard operation procedure of installation and dismantle of span by span construction of the bridges.
Results of the study indicated that factors lead to facility safety failures with injury and casualty also include lack of daily safety brief and education to the
labors, and ineffective field safety supervision throughout the entire span by
span bridge construction process related to: (1) records of deformation and dislocation of bridge span forms in the events of significant natural hazards such as storm, earthquake, and typhone, (2) inadequate or insufficient field supervision to avoid incorrect sequence, timing, and traffic interference during concrete pouring leading to instability sometimes collapse of the bridge span.
In the research , the causes of safety facility failures for the selected practical bridge projects were identified and studied to develop necessary improvement tactics to minimize the risk of injury and casualty resulted from facility safety failures during the similar cast in-situ span by span bridge constructions in the future.
