A simplified analysis model for determining the seismic response of buried steel pipes at strike-slip fault crossings
TL;DR: In this article, a simplified numerical model for buried steel pipes crossing strike-slip faults and oriented perpendicular to the fault is presented, which permits plastic hinge formations in the pipe due to incrementally applied fault movements, allows determination of the critical length of the pipeline and measure strains developed on the tension and compression sides in pipe.

Numerical Stress-Strain Analysis of Buried Steel Pipelines Crossing Active Strike-Slip Faults with an Emphasis on Fault Modeling Aspects
TL;DR: In this article, a 3D numerical model of a buried steel pipeline crossing an active tectonic fault is developed and discussed with an emphasis on the pipeline-soil interaction and mathematical representation of the fault.

Buckling behavior analysis of buried gas pipeline under strike-slip fault displacement
TL;DR: In this article, the effects of internal pressure, radius-thickness ratio and fault displacement on buckling mode and axial strain of buried pipeline were discussed. And the results show that buried pipeline in rock mass layer is more prone to failure than in soil mass layer under strike-slip fault.

Insights into the damage zones in fault-bend folds from geomechanical models and field data
Wei Ju,Guiting Hou,Bo Zhang +2 more
TL;DR: In this paper, the authors combine field observations and finite element models to calibrate the development and distribution of fractures in the fault-bend folds, and discuss the mechanical controls (e.g., the slip displacement, ramp cutoff angle, frictional coefficient of interlayers and faults) that are able to influence the development of fractures during faultbend folding.

Experimental and numerical modelling of buried pipelines crossing reverse faults
TL;DR: In this paper, the authors present results from a series of tests investigating the behaviour of continuous buried pipeline subjected to reverse fault motion and describe a new experimental setup for physical modelling of pipeline crossing reverse fault.

Fault Movement Effects on Buried Oil Pipeline
TL;DR: In this paper, the ability of a large diameter shallow-buried pipeline to withstand large fault displacements was studied parametrically, including variations in: (1) fault crossing angle, (2) unanchored length of pipe, (3) depth of burial, (4) wall thickness, (5) pipe diameter, and (6) pipe strength.
Journal ArticleDOI
Finite element analysis of buried steel pipelines under strike-slip fault displacements
TL;DR: In this article, the authors investigated the mechanical behavior of buried steel pipelines, crossing an active strike-slip tectonic fault, where the fault is normal to the pipeline direction and moves in the horizontal direction, causing stress and deformation in the pipeline.

Buried Pipe Design
TL;DR: In this paper, external load design of gravity flow pipes and pressure pipe design of pressure pipe buried pipe products are discussed. But they focus on external load and external load is not considered in this paper.

Stress analysis of buried steel pipelines at strike-slip fault crossings
TL;DR: In this paper, a beam-on-elastic-foundation and elastic-beam theory is used to calculate the axial force applied on the pipeline and adopts a combination of beamonelastic foundation and elastic beam theory to calculate its developing bending moment.
