摘要
结合工程实际,介绍了受火温度判定、火灾对混凝土材料的影响、火灾对结构受力的影响以及受损结构的修复等内容,对桥梁结构意外火灾的评价及鉴定,特别是预应力混凝土桥梁受火破坏的技术处理,具有借鉴意义。
In the light of actual engineering,the paper introduces judgement of temp sustarining fire,influence of conflagration on concrete materialss, influence of conflagration on load - bearing of structure as well as restoration of injured strurture, which possess reference significance to assessment and appraisal of unforeseen conflagration on bridge structure, especially to technical treapments for fire destroyed prestressed concrete bridge.
