Abstract

Mangjiedu Bridge is designed as a(116+220+116)m over-height pier and long span prestressed concrete continuous rigid-frame bridge with a 168 m main pier in height.The main pier will be drowned up to 166m when the reservoir retains water normally.In the paper,the design considerations,bridge span arrangement and structural design of the bridge are mainly introduced.
