空间缆自锚式悬索桥架缆模型工艺试验研究

Study on Technology Test of Space Cable Self-anchored Suspension Bridge Erecting Cable Model

杭州市江东大桥主桥采用空间缆自锚式悬索桥结构,中跨主缆架设需经历从空缆的竖直面内转换为成桥的倾斜面的过程。为进一步了解索股入槽、鼓丝、扭转等现象,进行了架缆模型工艺试验,有效地指导了缆吊系统的设计与施工。

The main bridge of Hangzhou Jiangdong Bridge uses the space cable self-anchored suspension bridge structure.The main cable of the middle span is required to transform from the vertical face of space cable to the incline face of the finished bridge.In order to further understand the phenomenon of cable strand into trough,wire twisting and birdcaging,the technological test of cable erection model is implemented efficiently to direct the design and construction of cable hoisting system.
