| Abstract: | A prestressed concrete extradosed cable-stayed bridge has three span,two pylons,and single-cable-plane.Spans are attributed as(80+128+80)m.The middle tower girder and pier are fixed.The side tower girder and pier are separated and supports mounted on the top of pier.Taking this bridge as an example,the characteristics of bridge type and force principle of the extradosed cable-stayed bridge are simply analyzed.In this paper,the analyses for design gist of this type bridge are mainly introduced,in which can p... |
