青海省某三跨空腹式双曲连拱桥承载性能试验研究

摘要

本文通过对某三跨空腹式双曲连拱桥进行静载试验、动载试验，分析了该其挠度校验系数和应变校验系数分布规律，并在动荷载试验基础上验证了桥梁在动荷载作用下的相关参数，为类似旧桥承载性能评价提供一定参考方法。%T his paper through the static and dynamic load test on a three-span empty hyperbolic multiple arch bridge to analyze the verification coefficient of deflection and the distribution law of verification coefficient of strain .Based on the dynamic test verify the related coefficient of bridge under dynamic load .Provide certain references to the bearing capability evaluation of similar old bridge .
