【摘要】 钢箱-混凝板叠合梁桥适合用于跨度大,且跨越较难断交的铁路、公路等设施的桥梁结构.本文通过荷载试验对新建成的某钢箱-混凝土板叠合梁进行了成桥承载能力检测,分析了该桥上部结构荷载作用下的响应特性,最终对该桥进行承载能力评定.试验采用的挠度、应变等参数的采集方法对今后类似工程检测具有参考价值.更多还原

【Abstract】 The bridge with steel-concrete composite girder is suit to the structure with long span which strides the railway and highway difficult to interrupt traffic. A new builtbridgewith steel-concrete composite girder was measured by loading test for static performance, furthermore, response characteristic under superstructure load was analyzed, finally, the bridge’s bearing capacity is estimated. The data acquisition means by detection and stress is a valuable reference for the detection to similar structures.更多还原
