【摘要】 河南洛阳嵩县龙驹桥修建于1975年.该桥全长46.0m,上部结构为单侧悬臂拼装式钢筋混凝土桁架结构,桥墩采用钢筋混凝土重力式墩,设计荷载为汽-15、挂-80.为了全面考察、检测桥梁结构的工作现状,选择悬臂跨进行了静、动载荷试验.根据检测结果对桥梁进行了健康评定并决定对该桥进行加固利用并提出一套加固设计方案.本文通过对该桥梁的检测评定与加固设计方案的探讨,试图找到一条旧危桥改造的新方法.更多还原

【Abstract】 The LongJu bridge46.0meters long’was built up in1975.Its upside structure is single-side cantilever assembling reinforced concrete truss with reinforced concrete gravity pier the designed loading is truck-15,trailer-80.In order to inspect the status of the bridge,the cantilever span is chosen to do static and dynamic loading test.According to the test results the healthy evaluation is made to put forward a set of reinforcing design and try to find out a new way for old and dangerous bridge reconstruction,meanwhile,the structure inspection,evaluation and reinforcement method is discussed.更多还原
