查询词典 plate girder

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.

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。
