摘要
山区高速公路隧道群近距离隧道洞口间设置遮光棚可以优化隧道的行驶环境,提高隧道间行车的安全,同时符合"四个交通"的发展要求。针对山西省天大高速公路大梁山特长隧道出口与黑石崖隧道进口之间增设遮光棚工程,运用Midas Civil~[1]有限元程序建立三维荷载结构模型,分析了隧道间设有横通道的遮光棚钢结构~[2-3]在不同荷载工况下的力学反应和变位规律,为日后类似遮光棚结构设计选型、后期管养提供了参考依据。
In view of the added shading-shed engineering between the Daliangshan extra-long tunnel exit and the extrance of Heishiya Tunnel of Tianda Highway in Shanxi Province. Using the Midas Civil finite element program, this paper established the three dimensional load structure model, analyzed the mechanical response and displacement law of the shading-shed steel structure setting with the transverse channel under the different load conditions between tunnels, which provided the reference for the design type selection, late management of the similar shading-shed structure in the future.
