The Huangpu suspension bridge catwalk system design uses the without wind-resist cables catwalk system, because its across the busy waterway waterway transportation. In this article, through wind tunnel tests the stability of wind-induced vibration of the catwalks is studied, then the test measured static aerodynamic coefficients is used to check the structural strength under two kinds of working conditions, operating mode A-catwalk to participate in the ropes of the force and operating mode B-not participate in the force, which is using the finite element method. The results show that this design meets the design requirements, and according to the proposed construction technology for construction guidance, we successfully completed the catwalk system of Huangpu suspension bridge construction.%由于珠江黄埔桥悬索桥所跨越水道水运交通繁忙,故设计采用无抗风缆的猫道系统.文中通过风洞试验对猫道的风致振动稳定性进行了研究,利用试验测得的静力三分力系数后,采用有限元法对猫道在扶手绳参与受力(工况A)及不参与受力(工况B)2种工况下的结构强度进行了验算,计算结果表明本设计方案符合相关设计要求,同时根据本文提出的施工工艺进行施工指导,顺利完成了珠江黄埔大桥悬索桥猫道系统的施工.
