| 摘 要： | 南京长江隧道工程江心洲右汉大桥为自锚式空间悬索桥，主缆从空缆状态到成桥状态，主缆横桥向位移较大，吊索须跟随主缆横向移动、转动及伸缩。通过一种新型的吊索结构，吊索可转动较大的角度，适应新型空间式悬索桥的问题，同时实现了吊索长度的调节。

| Abstract: | Right Branch Main Bridge in Jiangxin Island of Nanjing Yangtze River Tunnel Project is a spatial cable self-anchored suspension bridge. Main cable＇ s cross bridge displacement is large from cable-finished stage to dead-load state, and the hanger must move, rotate and flex with the main cable. We design a new hanger structure that can rotate a larger angle to adapt to the spatial suspension bridge, and it can also adjust the hanger＇s length. |
