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 and continuity of delivery to receiving locations. Due to soil movements such as landslides, excessive earth pressure imposed on buried pipelines causes damage and, consequen...

Modern countries utilise buried pipelines for the long-distance transportation of water, oil, and gas due to their efficiency and continuity of delivery to receiving locations.

This study investigated the stress distribution on a buried pipe induced by lateral soil displacement.
