摘要
该文将拉压杆模型应用到符合桥梁D区特点的斜拉桥索塔锚固区分析中,简化了索塔锚固区的预应力钢束的设计,采用该方法能够快速计算出锚固区的预应力钢束,为后续混凝土斜拉桥的类似设计提供了参考。
This paper analyed anchorage zone of cable-stayed bridge tower which conform to D-region of concrete bridges using strut-and-tie model. It simplified the design of anchorage zone. It can quickly calculate the amount of prestressed steel,and provides some references for design of similar PC cable-stayed bridges.
