在役中小跨度简支桥梁健康状况的简化评估

Simplified Assessment of Health Status on Medium and Small Span Simple-Supported Bridges in Service

在分层综合法与单项控制指标相结合的桥梁技术状况评估方法基础上做进一步的简化研究,探究一种简化、快捷的特别适合中小跨度简支桥梁的健康状况评估方法,并将研究结果应用于工程实例。算例表明,此方法是合理可行的,可为在役的中小跨度简支桥梁的健康状况评估提供参考。

Based on the method of the combination of stratified synthesis and single control index, this paper madeafurther simplified study on the basis of the method of bridge technology assessment. And it exploreda simplified andquick method for assessing the health status of medium and small span simply-supported girder bridge. The results wereapplied to the engineering examples, which indicates that this method is reasonable and feasible, which can providereference for the health status assessment of medium and small span simply-supported bridges in service.
