| 摘 要： | “321”装配式公路钢桥安全性评价的目的是要明确结构的实际安全储备，以避免在使用中发生灾难性后果。基于简单、实用的原则，建立了AHP与目测打分法、分析检算法、荷载试验法相结合的综合评价方法。即首先建立基于设计、制造和使用因素的钢桥安全性评价模型（AHP模型），进而提出了设计荷载、结构耐久性等九个评价指标的具体评分方法，然后利用关键构件裂纹长度修改系数来评价钢桥的安全等级。实例应用表明，该评价方法是可靠的。研究成果对同类结构的安全性评价工作具有指导意义。

| Abstract: | The safety assessment of type-321 portable steel bridge aims at determining the actual structural safety reserve of it,which helps avoid failing under operation.Based on the Analytic Hierarchy Process(AHP),scoring with visual inspection,loading test and rating load-carrying capacity coefficients,the safety assessment method of the bridge is established in the principle of being both simple and practical.Firstly,a comprehensive evaluation index system including design,manufacture and operation is proposed an... |
