Buried conduits are commonly used for utility transportation around the world. Accordingly, to ensure the safe design and installation of conduits, it is important to understand soil-conduit interaction. This research paper presents a numerical investigation of the structural response of a conduit buried within a soil slope in response to applied surface pressure. Numerically simulated and analytically calculated soil-conduit interaction results have been employed in the study to analyze the effect of crest distance and burial depth of a conduit on: its deflection, shape deformation, developed sectional normal stress and bending moment. The structural response of the conduit buried within the soil slope was also compared to that of conduit buried under level ground. The results show that conduit buried within a soil slope experiences more structural deflection and sectional forces than conduit buried under level ground, unless crest distance and burial depth of the conduit exceed approximately 5Bc and 3Bc, respectively; where Bc represents the outer diameter of the conduit. By using the graphical illustrations, explained mechanisms and developed correlations presented in this paper, practicing engineers can ensure the efficient design and installation of conduits buried within soil slopes.

埋在土坡内的管道结构响应的数值研究

埋地管道通常用于世界各地的公用事业运输。因此,为了确保管道的安全设计和安装,了解土壤与管道的相互作用非常重要。本研究论文对埋在土壤边坡内的管道对施加的表面压力的结构响应进行了数值研究。研究中采用数值模拟和解析计算的土壤-管道相互作用结果来分析管道的波峰距和埋藏深度对其挠度、形状变形、产生的截面法向应力和弯矩的影响。埋在土坡内的管道的结构响应也与埋在平地下的管道的结构响应进行了比较。5C3C, 分别; 在哪里C表示导管的外径。通过使用本文中提供的图示、解释机制和发展的相关性,实践工程师可以确保埋在土坡内的管道的有效设计和安装。
