Abstract
Ensuring the strength of the structural solution when laying gas pipelines in earthquake-prone areas
Incoming article date: 17.06.2025The article considers the influence of seismic load at different points on underground polyethylene gas pipelines in areas of possible earthquakes. It is revealed that the seismic load is the main load affecting underground gas pipelines. The critical ratio of the bending radius to the diameter of the gas pipeline is investigated. It is proved that with a bending radius of at least 25 pipe diameters, the pipeline retains its strength in areas with increased seismic hazard.
Keywords: underground gas pipelines, seismic activity, loads, bending radius, structural strength
