摘　　要：针对贵州镇胜公路北盘江大桥为贵州山区修建的主跨636 m的钢桁梁悬索桥,介绍了该桥的主索鞍和散索鞍设计,通过有限元分析验证了手工简化计算结果,找出能反映索鞍真实受力情况的手工简化计算方法。Taking the 636 m long suspension bridge at Beipan river Zhen-Sheng road in Guizhou which is built for Guizhou province for example, this paper introduces design of main cable saddle and vice cable saddle of the bridge, analyzing and validating the simplified calculation result by hand by using finite element. It also finds out the hand simplified calculating methods which could reflect the real force sustaining situation of the cable saddle.

关 键 词：悬索桥 主索鞍 散索鞍 有限元分析 设计
