The protection of pipelines from natural hazards is an important task for engineers, as any damage would result in loss of functionality and possible release of environmentally dangerous substances, if they are used for the transportation of hydrocarbons. The uplift of a gas buried pipeline in loose saturated sandy soil deposit caused by earthquake-induced liquefaction phenomenon has been studied through shaking table tests in a model scale of 1:10. The experiments were conducted at the geotechnical laboratory of the University of Tokyo. In this paper, the results of four different tests will be presented: an innovative protection system, constituted by gravel bags, placed above or below the pipe has been proven to be effective in mitigating the uplift effects through a low-cost technology.

Abstract
The protection of pipelines from natural hazards is an important task for engineers, as any damage would result in loss of functionality and possible release of environmentally dangerous substances, if they are used for the transportation of hydrocarbons. The uplift of a gas buried pipeline in loose saturated sandy soil deposit caused by earthquake-induced liquefaction phenomenon has been studied through shaking table tests in a model scale of 1:10. The experiments were conducted at the geotechnical laboratory of the University of Tokyo. In this paper, the results of four different tests will be presented: an innovative protection system, constituted by gravel bags, placed above or below the pipe has been proven to be effective in mitigating the uplift effects through a low-cost technology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
