摘要
以一座三跨空腹式双曲拱桥为例,介绍了双曲拱桥的构造及受力特点,并对桥梁空间结构简化为平面杆系结构进行承载能力理论分析。通过静载试验,把理论值和实测值进行对比,验证了单片拱肋模型计算结构受力是比较安全的,为双曲拱桥承载能力评定提供了更多依据。
Taking a three-span double arch bridge as an example,the structure and stress characteristics of double arch bridge are introduced in the paper. The spatial structure of the bridge is simplified to plane truss structure,and the carrying capacity of the bridge is analyzed in theory. The theoretical values and the measured values of the static load test are compared,and the test results show that the stress of single arch rib structure is relatively safe,which provides more references for evaluating the carrying capacity of double arch bridge.
