摘    要:索道桥是以钢丝绳为主要受力构件的一种柔性悬索体系桥梁,在临时工程及战备中占有重要地位,为此建立准确的模型和建成后的承载能力评估具有重要意义。本文利用有限元软件建立了大河家索道桥的空间计算模型,通过数据的对比分析后其静力计算结果与试验的静力实测结果基本吻合,验证了设计理论的合理性以及计算的正确性。所得结果及计算过程可为同类索道桥设计提供参考。

关 键 词:索道桥  有限元分析  静力分析  索力

Abstract:Cable bridge plays an important role in temporary works and readiness,which is one kind of flexible cable system bridge whose main stress components are steel wire ropes.Therefore,to establish accurate models and to assess the bridge’s bearing capacity after the construction has important significance.In this paper,the calculation model of the bridge was established by the finite element software.The calculated results are consistent with the test results after comparison.The result verified that the design theory is rational and computation is correct.The obtained results and calculation process could be referenced for similar bridge design.
Keywords:Cable bridge   Finite element analysis   Static analysis   Cable force
