| Abstract: | The bridge is a prestressed concrete long span T_type cantilever girder bridge with high pier. The cross section is a prestressed concrete single box girder. The reinforced concrete pier is a hollow box pier of varying cross section. According to the structural properties of the bridge, the space beam element is used to divide the bridge. The dynamic characters and seismic response are made. Some useful conclusions which used as the basis of designing are given. |
