In the current industry practice guidelines, the soil restraints to assess the behaviour of pipelines subject to permanent ground displacements are numerically characterized using independent “soil springs”. These guidelines have been primarily generated by...

This paper presents a thermo-hydro-mechanics theory and corresponding computational framework to capture the freeze thaw action of frozen porous media and associated frost action under chilled gas pipelines. Based on the mixture theory, frost-susceptible soils are...

Current industry practice for the pipe–soil interaction analysis widely uses either American Lifeline Alliance(ALA)or Pipeline Research Council International(PRCI)guidelines to model the soil load exerted on the pipeline. The maximum lateral force for the lateral soil...

The sudden and mostly unpredictable landslides in sensitive clay are generally retrogressive in nature and eventually turn into a flow of failed soil mass that exerts force on the pipeline placed across the route of the flow (drag). The drag force is one of key design...

Seepage plays a significant role in many geotechnical problems such as the stability of earth dams and riverbanks. In addition, the large-deformation behavior of soil is equally important in many cases, including progressive failure of slopes, and landslides in...
