Design of Continuous Rigid-frame Railway Bridges with Low Piers a Humdred Plus Meters High |

| Abstract: | Based on the prestressed concrete continuous rigid-frame of the main bridge(68+128+68)of Sancao Bay super large bridge over the Xuda railway,the author introduces the design of steel bridge with low piers a hundred plus meters high and analyzes the static characteristics of such kind of bridge and dynamic response of main bridge.These can provide valuable references to solve the problem of stiffness difference in designing continuous rigid-frame bridges with low piers high and reasonably practice the beam stress that distributes the stress of low piers of a hundred plus meters high. |
