| 摘 要： | 在分析现有桥梁加宽改造效果结构安全性和适用性评价方法的基础上,针对公路装配式空心板桥加宽,提出了基于结构静力荷载试验检测的新旧结构连接性能评价方法,通过评价新旧结构的连接性能来评价桥梁的加宽改造效果,并应用到杜河桥加宽改造效果评价工程实践中,结果表明,该方法具有直观性、可靠性特点,可用于类似桥型加宽改造效果评价.

| Abstract: | Based on the subsistent effect evaluation method of structural security applicability highway for bridge widening analysis,a new method is advanced for highway prefabricated cellular slab bridge widening effect evaluation. It is realized by new quondam structure joint performance which is induced from bridge field load testing. This effect evaluation method is successfully applied to Duhe bridge widening project,and can be applied to similar bridge. |
