Are our oil and gas pipelines safe during an earthquake?
E-Mail IMAGE: The new research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect. view more Credit: Peter the Great St.Petersburg Polytechnic University 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. Since then, a number of methodologies were propo...
