Long-term response of flexible pipe in sand trench due to consolidation of native clay

The finite element analysis are performed to investigate a long-term response of flexible pipe buried in sand trench embedded in native soft clay. The investigated long-term behaviors are due to effects of backfill soil structure rearrangement and native clay consolidation. The finite element results suggest that the short-term response of pipe depends strongly on trench widths but independent of trench depths due to the dependence of arching...
