斜拉桥同向回转锚索系统设计方法

Design method of rotary anchor cable system of cable stayed bridge

介绍了一种原创新型的斜拉桥锚索系统——同向回转锚索系统,这一系统从受力机理上规避混凝土桥塔受拉开裂的缺陷,通过一系列细致的理论及试验研究,总结了一套成熟的设计方法,并成功应用于多座大跨径斜拉桥,为今后同类桥梁设计提供了一种新的思路。

This paper introduces a new type of anchor cable system of cable-stayed bridge,which is the rotary anchor cable system. The system avoids the tensile crack of concrete bridge from the force mechanism. After a series of detailed theoretical and experimental studies,a mature design method is summarized by us,and it has been successfully applied in many large span cable-stayed bridges. This design method provides a new idea for the design of similar bridges in the future.
