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 proposed for calculating stress received by an underground pipeline during an earthquake. The purpose of these methodologies was to make an accurate prediction on the structural stress received by a pipeline during an earthquake, and thus it would allow to decide how resilient the pipeline must be made in the first place. It is important to find a right balance between pipeline cost and its structural resilience.
