摘　　要：某双塔三跨预应力混凝土单索面部分斜拉桥,孔跨为80+128+80=288m,采用塔梁固结、塔墩分离的结构体系,墩顶设支座的结构形式。以该桥为例,浅析了预应力混凝土部分斜拉桥的桥型特点、受力特性,主要论述了该类桥型的设计计算分析要点,可以为同类桥梁的设计提供参考。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 provide references for other similar bridges design.
