    摘要
  • 摘要: 综合管廊是非常重要的基础设施，波纹钢综合管廊具有明显的优势。通过对一种新型波纹钢综合管廊的受力性能进行试验研究，采用有限元方法对附属结构的连接节点进行分析，并对其进行系统化参数分析。研究结果显示：多拱波纹钢综合管廊跨顶板中应力较高，顶板中存在反弯点；角板的应力较低，且没有出现应力集中；侧板为轴压构件，整体应力较低；结构的竖直变形主要发生在顶板中，且水平变形明显小于竖直变形；通风管的厚度对节点应力集中有明显影响，当管直径为700 mm时，最优厚度为4 mm；通风管的最优位置位于顶板跨中，当两个通风管间距大于通风管直径时，管廊顶板的结构响应几乎不受影响。
    Abstract: The utility tunnel is an important infrastructure facility in which corrugated steel structures exhibit significant advantages. An experimental study was conducted on the mechanical properties of a new type of corrugated steel utility tunnel. Subsequently， the connections of its auxiliary structures were analyzed using the finite element method. Finally， a systematic parametric study was conducted on the connections. The results indicated that the mid-span stress of the roof plate in the multi-arch corrugated steel utility tunnel was relatively high， with the presence of a contra-flexure point； the stress of the corner plate was relatively low， with no stress concentration； and the side plate was a compression-flexural member， exhibiting a relatively low overall stress. Vertical deformation was primarily concentrated in the roof plate， while horizontal deformation was significantly smaller than vertical deformation. The thickness of the vent pipe had a significant impact on stress concentration； when the diameter of the vent pipe was 700 mm， the optimal thickness of the vent pipe was 4 mm； the optimal position of the vent pipe was located at the mid-span of the roof plate； and the response of the intermediate part remained almost unchanged when the spacing between two vent pipes was greater than the diameter of the vent pipe.
