Overview

Randomized trial investigates pipeline loads under subsidence, highlighting the importance of soil interaction.

Key Points

  • This research aims to evaluate the effects of localized subsidence on pipeline loads using a three-dimensional soil-arch model.
  • Investigated 3D transfer characteristics of vertical loads on buried pipelines under localized subsidence.
  • Established a 3D soil arching model considering overburden self-weight and lateral earth pressure.
  • Constructed a load-transfer framework and derived an analytical expression for the vertical load at the pipe crown.
  • Demonstrated significant differences in pipeline crown loads between tests (p<0.01) and variations in vertical earth pressure with trapdoor displacement.
  • Revealed that the proposed model accurately represents stress redistribution in deformation zones associated with pipe–soil interaction.
  • Validated predictions against laboratory trapdoor test data, showing enhanced explanatory power compared to traditional methods.
