摘　　要：论述了部分斜拉桥的塔梁固结和刚构2种常用的结构体系,以及新式V型桥塔在部分斜拉桥中的应用;分析了在中跨满布汽车荷载作用下3种桥型的内力和位移。结果表明,单柱塔的2种体系在各自适用范围内有其特有的优势,而新式V型桥塔作为新兴的发展方向也有单柱塔所不能比拟的特点。The different combination models of cables, towers, beams, piers of partially cable-stayed bridge can compose different structure systems. The paper discusses pin-jointed deck/tower condition and rigid deck/tower condition and the application of V-shaped tower in partially cable-stayed bridge. The results indicate the two systems of single leg towers have their superiority in their application area, but the V-shaped tower has its characteristic as a new way.
