The Force Analysis And Experiment Capability Research Of Middle Supporting Arch Bridge

With the flourish development of the highway, the construction of the bridge develop very fast .In the lots type of bridges ,the arch bridge is a very common system in our country. The arch bridge has a lot of virtues : it's span could be so large, the materials of the arch bridge can be got very easily ,the shape of this type is very beautiful and the structure is simple. In the future ,the arch bridge will be also very important type .Nowadays the arch bridge type is changing to light and large span .In lots of large span arch bridges ,the middle supporting arch bridge is a very familiar type .In this paper ,the structure and force calculation of the middle supporting arch bridge are introduced .The more important content is the static and dynamic experiment of the Yinhe bridge ,which locates in NeiMeng Province.With this experiment ,we analysed the bridge's technique status .bearing capacity and dynamic capability .All of these would provide many experiences for this bridge type in design and construction .
