特别是上世纪九十年代以后，在我国修建的一系列跨江跨海特大型桥梁中，很多桥梁上部结构采用了钢结构。 - In allusion to this problem , detailed investigations were made in this article . on the base of these data , we analyze reasons of scathes of bridges . local damage of bridges is much serious
桥梁上部结构的损坏造成了其使用寿命的缩短，本文针对这一问题，作了详细的调研，并在此基础上对上部结构产生病害的原因进行了分析。 - Grillage girder is always used for analysis the structures , such as dense ribbed slab , superstructure of bridge and grid - mat foundation . in this paper , a mechanical model for grillage girder by elastic supporting is proposed , and used for analysis the track structure for the first
交叉梁系一般用于求解密肋式屋面板、桥梁上部结构和格式基础等结构，本文提出一种弹性支承交叉梁系模型，并首次用其求解轨道结构。 - The paper is based on an arcuated built - up system bridge - zhongshan no . one bridge to be built in guangzhou , adopts the large universal finite element programme ansys , takes spatial action among members into account , establishes a three - dimension finite element model , and discusses the following several aspects : firstly , when three - dimensional finite model of a complicated bridge is founded , a beam - lattice method is a kind of applied and effective spatial analysis method , which is used to analyze superstructures of a bridge
本文以广州市中山一桥为背景，采用大型通用有限元程序ansys ，考虑构件间的空间相互作用，建立了三维的有限元模型，重点对以下几个方面进行深入探讨：首先，在对复杂的桥梁结构进行三维的有限元模型建立时，梁格法是分析桥梁上部结构比较实用而且有效的空间分析方法。 - The vibration of upper structure of bridge which caused by the dynamic action of vehicle pass the railway bridge may make the structural component fatigue and decrease the intensity and stability . the more vibration of bridge will influence the safety and stability of vehicles ; when the dynamic changing frequency of vehicle equal or approach to the free vibrational frequency of bridge , wh ich will make the resonance may intensify the response of bridge and vehicles
列车动力作用引起桥梁上部结构的振动可能使结构构件产生疲劳，降低其强度和稳定性；桥梁振动过大可能会对桥上车辆的运行安全和稳定性产生影响；当列车的动力变化频率与桥跨结构自振频率相等或接近时，引起的共振可能会使车桥动力响应加剧。
