A Review: Study of Water Pipe and Soil Interaction during Passage of Strike-Slip Fault Download PDF

Pipelines may be ruptured due to large deformation caused by faults, liquefaction or instability of slopes. Safe and effective designing pipelines when crossing fault is one of major challenges facing pipelines’ designers.The thesis studies reaction of a metal pipeline to the motion of a strike-slip fault. Soil and pipe interaction investigated by considering two types of soil: very sticky and weak granular soil under fault displacement. There has been used steel API5L grade.x65 for the pipelines.Since tension and strain are more near the fault, elements have been considered smaller near the fault and larger in other points. There has been modeled a fault by taking a fixed block and displacing to movable block and interaction of soil-pipe by entering mechanical properties of soil and pipe to software.
