| 摘 要： | 20世纪70年代以来,我国修建了大量的钢筋混凝土箱形拱桥,在一定程度上促进了拱桥向大跨度的发展。该文基于设计文件,利用ANSYS软件建立了球溪河大桥的空间有限元模型,计算了该桥的自振频率和模态,并得出了一些有用的结论。

| Abstract: | Since the 1970s,a great deal of reinforced concrete box arch bridges has been constructed in our country.To some extent it promotes the development of the long-span arch bridge.A 3-D finite element model is built on the base of design drawings of Qiuxi River Bridge with ANSYS in this thesis,and the natural vibration frequencies and modes are figured out,and some useful conclusions are drawn. |
