- This thesis will emphasis research the technique of reinforcing experiment test on the top - bear type armor plate the beam , especially to the 40 - meter top - bear type armor plate beams of the big bridge of yellow river of zhengzhou
本文重点研究上承式钢板梁特别对京广郑州黄河大桥40米上承式钢板梁的加固技术实验测试。 - With the actual locale incestigating , the actual locale testing and the theories analyzing of the reason of the diseases producing of the exceed limit of horizontal swing and steel pole ' s break , and summaried the reinforcing measure of the top bear armor plate beam
通过对京广线郑州黄河大桥40米上承式钢板梁横向摆动严重超限及钢梁杆件断裂等情况的现场调查、现场测试和理论分析及病害原因产生的机理，总结提出了上承式钢板梁的加固措施。 - For do n ' t delive the horizontal power , connect method adopt the double hingle connect , and made both girder just to deliver the horizontal power each other , and vertical power can change position , this the problem that the top bear armor plate beam do n ' t accommodate the increasing in speed had been resolved radical
为了不传递竖向力，连接方式采用双铰接，使两孔梁只能相互传递横向力，竖向可以变位，从而基本解决了上承式钢板梁不适应提速问题。 - Because of the original design standard was low , the horizontal angur rigidity is serious lack , when the high speed train passes , the exceed limit of the horizontal swing had affected the lifting of the main trunk line , these diseases had been existed earlier but had not been gotten to resolve radical , and along with the increasing in speed of railroad train , these diseases performance will be more seriously , it ' s time for resolve
同时提速列车对桥梁结构的动力作用增大，特别是对上承式钢板梁。由于原设计标准低，横向刚度严重不足，高速列车通过时横向摆动严重超限等已严重影响了主要干线的提速，这些病害很早就存在但没有得到根治，随着列车提速，这些病害表现越来越严重，已到了必须整治的时候了。 - Based on qualitative analysis and comparison of several options for suppressing transverse vibration on deck type steel plate girder of railway bridge , conclusions are made as follows : with static reinforcing , the vibration amplitude can be suppressed to some extent , but quasi - resonance of the bridge can not be avoided , moreover , the construction is inconvenient and costly . with option of two bridge connection , the effectiveness of vibration suppression is clear ( the damping ratio approaches 50 % ) and it is fairly economic and easy , however , the quasi - resonance of the bridge can not be avoided either . with dynamic option ( mtmd option ) , the quasi - resonance of the bridge can be effectively avoided ( the damping ratio is up to 51 . 38 % as tested in field ) , moreover , the construction cost is low , and the construction is simply and convenient
通过对目前抑制铁路上承式钢板梁桥横向振动的几种方案进行定性的分析和比较，认为：静力加固方案可以使桥梁振幅有所减小，但不能避免准共振现象的发生，而且工程造价较高，施工也不方便；两桥连接方案减振效果明显(减振率近50 % ) ，比较经济也比较方便，但同样不能避免准共振现象的发生；动力减振方案( mtmd抑振方案)可以有效的抑制桥梁的准共振现象(现场试验中减振率达51 . 83 % ) ，而且工程造价较低，施工简单、方便。
