摘　　要：索道桥是以拉索作为主要受力构件,钢横梁及木板等作为局部受力构件的一种悬索体系桥梁,其作为非永久使用桥梁,目前我国还没有关于其设计施工的标准。本文以某工程大跨度索道桥为例,运用有限元软件MIDAS/civil对索力及横向稳定性进行了计算分析,并对拉索、钢横梁、锚杆的设计进行了验算,所得结果及计算过程可为类似索道桥提供参考。Cable bridge is a type of suspension bridge which depends on the wire rope to suffer the external force, however, as the non-permanently used bridge, there are no standards of design and construction for this kind of bridge in China . In this paper, taking a long span cable bridge as an example, calculation and analysis were carried on the cable force and lateral stability by the finite element program Midas/Civil, as well as the checking of cables force, steel beams and the anchor design. The analysis approach and the conclusion are useful for the similar cable bridge.
