With the fast development of underground space engineering, it is inevitable for buried pipelines to be crossed by twin tunnels. Previous studies mainly focused on single-tunneling effects pipelines. To emphasize twin-tunneling pipelines, we first examined effectiveness ground settlement prediction method under conditions. Then, estimated boundary condition was applied beam-on-spring finite ele...

Abstract Detailed study of the response pipelines during seismic excitation can help reduce physical and financial losses after an earthquake. The current research investigated behavior passing through variations in topography using two-dimensional three-dimensional modeling. Their has been modeled at crest toe a slope longitudinal passage topography. effects soil stiffness, diameter-to-thickne...

offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. a safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. while the cost...
