Abstract
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.
