摘　　要：根据多个猫道设计的经验,对官山大桥猫道的设计难点进行了简明分析,结合该桥地处台风区,风速特大的事实,探讨了官山大桥猫道的整体设计,尤其是对猫道的选型、横向通道的数量、断面尺寸的确定和塔顶锚固结构均进行了较详细地介绍,最终研究了猫道的抗风稳定性,并给出了详细结论。According the design experience to catwalks, a brief analysis to the hard and difficult points for the Guanshan Bridge is made in this paper. The bridge is situated in a typhoon zone where the velocity is quite large. The overall design of the catwalk, particularly the types selection, the number of the transverse passageway, section diamension and the anchoring structure at top of the tower are introduced in detail comparatively, finally the wind-resistance stability of catwalk is studied, and a detailed conclusion is proposed.
