A Large-Scale Model of Lateral Pressure on a Buried Pipeline in Medium Dense Sand

Modern countries utilise buried pipelines for the long-distance transportation of water, oil, and gas due to their efficiency continuity delivery receiving locations. Due soil movements such as landslides, excessive earth pressure imposed on causes damage and, consequently, leaking liquids, gases or other harmful effluents into soil, groundwater, atmosphere. By using a large-scale physical model, lateral pipeline–soil interaction in sandy was researched. This study investigated stress distribution pipe induced by displacement. The external forces caused surrounding motion were measured cells installed active zone along pipeline. Additionally, visual inspection ground deformation patterns surface, including tensile cracks, above shallow-buried pipeline subjected movement reported. results revealed that has potency effect pipelines. findings also indicated highest stresses occur at unstable boundaries prior reaching soil’s peak strength. After observing surface’s rupture, most increments concentrated middle section pipe.
