Abstract: Case studies of pipeline repairs following extreme ground movement events demonstrate how the displacement accommodating mechanisms of hybrid-segmented pipelines perform favorably (requiring less repairs to maintain ...

Abstract: Buried pipelines subjected to permanent ground deformations (through, e.g., earthquake-induced liquefaction or fault rupture) often experience widespread damage. Regardless of the direction of ground movement, pipelines ...

Abstract: Most natural granular deposits are spatially variable due to heterogeneities in soil hydraulic conductivity, layer thickness, relative density, and continuity. However, existing simplified liquefaction evaluation procedures ...

Abstract: Cured-in-place linings (CIPLs) are flexible fiber-reinforced polymer linings used to rehabilitate aging pipelines in situ. They also can strengthen utilities against transient and permanent ground deformation caused by ...

Abstract: Dense granular columns (DGCs) are generally known to mitigate the liquefaction hazard through a combination of (1) installation-induced ground densification, (2) enhanced drainage, and (3) shear reinforcement. ...
