Structural response of the spiral-welded pipelines buried in different uniform soil types to the strike-slip fault

Journal of Pipeline Science and Engineering, 2023
Buried steel pipelines, which are widely used in, often face the threat of Permanent Ground Deformations (PGD) caused by fault crossings. The structural response of the pipeline can be influenced by the pipe-trench-backfill interaction, resulting in ...
