Share Underground pipelines that transport oil and gas are very important engineering communications worldwide. Some of these underground communications are built and operated in earthquake-prone areas. Seismic safety or seismic stability of underground pipelines began to be intensively studied since the 1950s. The research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect Since then, a number of methodologies were pr...
