According to different mechanisms , there exist several types of resonance , including the bridge resonance induced by the periodical actions of moving load series of the weights , centrifugal forces and lateral winds of vehicles , the bridge resonance induced by the loading rates of moving load series of vehicles , the bridge resonance induced by the periodical loading of train vehicles excited by rail irregularities , wheel flats and hunting movements , and the vehicle resonance induced by periodical actions of the regular arrangement of bridge spans and their deflections 根据发生机理的不同，车桥系统可能发生几种不同形式的共振，包括由车辆重量、离心力、横向平均风荷载等形成移动荷载列的周期性动力作用引起的桥梁共振，由移动荷载列加载速率引起的桥梁共振，由轨道不平顺、车轮扁疤、轮对蛇行等周期性加载引起的桥梁共振；由桥跨的规则性排列及其挠度的影响，对移动车辆形成周期性动力作用使车辆出现的共振。
Further , the design theory and method of the dam and the foundations of buildings are also used for reference . a series of design thoughts , design principle and design method of the standard section form stability design , settlement design and foundations design and processing of the dam - like embankment design are putted out . the present dam - like embankment is appraised based on the theory 本文在分析坝式路堤将产生的社会、环境效益的基础上，对其经济性与高路堤及桥跨结构进行了对比，并将土坝和建筑地基设计理论和方法引入公路坝式路堤设计，提出了关于坝式路堤设计的结构型式、稳定设计、沉降设计、地基设计等一整套方法。
Taking the south approach of the sutong bridge as example , the interaction of the adjacent spans in the longitudinal and lateral direction is discussed in this paper , comparing the results according to specifications of earthquake resistant design for highway engineering with the results from fem analysis 摘要本文以苏通大桥南引桥为例，按照现行《公路工程抗震设计规范》提供的相关计算公式与有限元的计算结果进行比较分析，探讨了梁桥纵横向相邻桥跨之间的耦联作用。
Abstract : with the increasing of suspension bridge ? s span , the gravity stiffness of suspension cable itself is more important than vertical deflection resistance stiffness of stiffening girder which is serviced for the whole structure . in order to provide more knowledge of gravity stiffness of suspension cable , in this paper , gravity stiffness of suspension cable is formulated briefly and theoretically in case of ignoring the existing of the stiffening girder . the deformation and internal force of suspension cable can be calculated approximately in this way 文摘:随着悬索桥跨度的增大，加劲梁的竖向抗弯刚度提供给整个桥跨结构的刚度仅占次要地位，而悬索自身的重力刚度却占有重要的作用.为加深对重力刚度的进一步认识，笔者对特大跨度的悬索桥的重力刚度进行简要的理论推导，在忽略加劲梁存在的情况下，可近似地计算悬索桥的变形和内力
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。
Especially the bridge engineering has to be concerned with high , new and difficult technologies . new technologies firstly adopted are post - tensioned prestressed concrete simply - supported box girder , assembly two - way prestressed concrete simply - supported t - girder , reinforced concrete continuous rigid frame , and steel - concrete composite continuous girder . all these have formed a series of new bridge structures taking prestressed concrete simply - supported box girder as main feature 由于秦沈客运专线的特殊技术要求，在铁路建设史上首次采用了后张法预应力混凝土箱形简支梁、装配式双向预应力混凝土t形简支梁、钢筋混凝土刚构连续梁、钢与混凝土结合连续梁等桥跨结构，形成了以预应力简支箱梁桥跨结构为主要特征的一系列桥梁新结构。
Abstract : interchange bridge is an important part of interchange , and it affects the overall view of interchange . this paper summarizes the characteristics and design acquirements first , and then the outline of bridge aesthetics from both the overhead structure and the supporting structure , in order to guide , evaluate and intact the planning and designing of interchange 文摘:立交桥跨是互通式立交的主要组成部分，桥跨直接影响立交整体美观.笔者首先阐述互通式立交桥跨的美学特征及美学设计要求.然后从上部构造和下部构造等方面来说明立交桥跨的美学要点，力求从立交桥跨美学角度来指导、评估和完善立交规划与设计
