Ultimate Bearing Capacity of Pipe Buried Near Sand Slopes
In hilly areas, the pipelines may be subjected to external forces due to slope topographic, which possibly might lead to leakage of hazardous liquid or gas into the environment. The slope angle may play a significant role to the soil-pipeline interaction. And many constrictions of commercial or industrial building is done above the pipe lines in hilly areas, which may lead damages of pipes within the slopes. The present research aims to study the ultimate bearing capacity of the pipelines buried in dry sand slopes. The two-dimensional finite element limit analysis (2D-FELA) is used for the present numerical analysis. The Mohr–Coulomb (MC) failure criterion with associate flow rule is assumed for the present FELA analysis. While the buried pipe is fully rigid with thickness of 120 mm. The ultimate bearing capacity of buried pipe corresponding to the internal friction angle of the soils is examined under vertical load. The effect of slope angles on bearing capacity of buried pipe and failure wedges formed beneath the buried pipe is also studied in the present work. The present FELA results concludes that the bearing capacity of buried pipe decreases as slope angle increases. Whereas, with the decrease of edge distance of pipe from crest of the slopes, the two-sided wedge failure beneath the buried pipe becomes one sided wedge failure.
