五跨连续刚构桥承载力评定

摘要

为判断五跨连续刚构桥梁在试验荷载作用下的实际工作性能和承栽力，评价桥梁的施工质量，通过静载试验测定桥跨结构的静应变、静挠度等静力效应；通过动载试验测定桥跨结构的动应变、自振频率、冲击系数等动力性能，进而对桥梁结构的承载能力进行了综合评定。%A five span continuous rigid frame bridge in Zhejiang province employs two separate type two tank four-chambered structure box girder and V pier. To evaluate its actual performance and bearing capacity under test load and construction quality, made to check bridge span structure static strain, static deflection and dynamic load test is done to check bridge span structure dynamic strain, natural vibration frequency, impact coefficient. A comprehensive evaluation is given to the bridge structure load performance.
