  3. Abstract:
  4. The land-sliding forces applied to buried pipelines depend on the ground condition, types of loading and pipelines features. This paper intends to numerically investigate the effect of ground condition on pipelines. The loading type and pipeline features are kept constant. The pipeline which is positioned at mid-length of the slope, is made of steel and intersects the slope at the angle of 90o. The slope material specifications are determined based on geotechnical reports andthe harmonic loading simulates a 7.5 magnitude earthquake. The descending trend of slope displacement in sandy clay, loose to medium sand, cemented sand and medium to hard clayare shown by numerical calculations. But, the deformations of buried pipes do not follow thistrend. As the cemented sand causes the buried pipe to deform the highest. The pipes embedded in the sandy clay, loose to medium sand and medium to hard clay slopes show lower deformations respectively. © 2019 Associazione Geotecnica Italiana, Rome, Italy
