| Abstract: | The single tower prestressed concrete cable stayed bridge with a span of (50 + 82 + 180) m is adopted in the main bridge of Xiantao Hanjiang highway bridge in Hubei Province. The tower is in rigid connection with the girder. The seismic intensity at the bridge site is 7 degree. The anti-seismic performance is specially important as it is an extra large bridge across Hanjiang. The design and research work, including the safety evaluation of the bridge site and the seismic load calculations, etc. are presented. |
