Abstract:

This paper presents the effect of burial depth on the response of conventional buried pipelines under strike-slip fault rupture and also proposes a mitigation method using geofoam blocks to safeguard buried pipelines. The performance of the buried pipelines is assessed using three-dimensional numerical simulation using ABAQUS. The configuration of geofoam blocks for protection consists of two blocks at each side of the pipeline and one block on the top of pipeline. The results shows that although the conventional buried pipeline failed due to fault rupture as a result of excessive compressive strain as well as local buckling within the pipe wall, geofoam blocks could successfully reduce the compressive and tensile strains along the pipeline satisfying the design requirements.
