摘　　要：对依兰牡丹江大桥、福建石潭溪大桥和丫髻沙大桥的设计、振动病害和动力改造设计进行了分析,得出悬吊式桥面系纵向联系刚度太弱导致桥面系的整体性较差,通过对日本新西海桥的设计和动力性能的研究,证明了采用纵向刚度较大的纵横梁格体系作为桥面系结构,在重车作用下具有良好的动力性能。Compared the design,vibration disease and the dynamic performance improving design of the Yilan Mudanjiang Bridge,Fujian Shitanxi bridge,Yajisha bridge.It is confirmed that the longitudinal contact stiffness is too weak of the suspended deck system,lead to poor integrity of the bridge deck system,by studying the Japan new saikai bridge＇ design and the dynamic performance,showed that the application of strong vertical stiffness gider and horizontal girder system as the floor system structure,has good dynamic performance under the action of a heavy vehicle.
