1、随着我国交通事业的迅猛发展,桥梁作为交通中的重要一环,在发展经济的过 程中起着非常重要的左右。近年来,国内兴建了各式各样的桥梁,这些桥梁在建设和使用过程中都需要对其进行实时监测,以确保建设的顺利进行和安全使用。如今的各类桥梁,由于各种因素的影响,会不同程度的出现一些问题,如承载力,刚度以及耐久性降低等,影响其寿命,甚至严重的发生坍塌事故。因此都既有桥梁的安全性进行评估具有十分重要的意义。桥梁试验在桥梁结构健康检测中起了重要的作用,其目的是通过试验,掌握桥梁结构的实际工作状态,判断桥梁结构的承载能力和使用条件,检验设计与施工质量。本文通过现场静载和动载试验,结合理论分析,确定魏荆输油管道汉江管桥
2、的实际承载力水平和动力特性。并结合其他检测,综合分析评价桥梁的技术状况,对桥梁的运营现状提出正确合理的结论,并为今后的维修、加固补强提供了详实的技术资料。本文在如下几个方面进行了理论和试验研究,并取得了一些研究成果:1)基于ANSYS建立了桥梁结构有限元模型,其中包括结构总体模型和钢桥塔模型,进行了理论上的分析;2)通过桥梁结构理论计算结果和实测结果的比较,同时结合其他检测手段,对桥梁的健康状况进行了评估。关键词:桥梁结构;静动载试验;ANSYS;有限元AbstractWith the rapid development of Chinas transport, traffic in the
