Soil restraint on buckling oil and gas pipelines buried in lumpy clay fill

Laboratory tests and thermal buckling analysis for pipes buried in Bohai soft clay

“…However, such analytical solutions greatly depend on the simplifications and assumptions made during their formulation, and thus, differ from the true conditions present in the field. Numerical analysis is a viable alternative to overcome the difficulties in finding exact analytical solutions for such a complex problem [5,6,10,12,13,25,33,34].…”

Modelling of upheaval buckling of offshore pipeline buried in clay soil using genetic programming

“…However, very limited number of studies was reported in the literature for pipe buried in clayey soils. Recently, Cheuk et al [7] and Thusyanthan et al [26] reported the experimental work to understand the uplift resistance of clay. However, the effect of variability in soil properties in uplift resistance has not been quantified, which requires significantly high number of experiments.…”

Offshore pipeline performance evaluation by different artificial neural networks approaches

“…However, most of the experimental works on uplift resistance were carried out in granular soils and very limited http://dx.doi.org/10.1016/j.measurement.2015.08.035 0263-2241/Ó 2015 Elsevier Ltd. All rights reserved. experimental studies were reported in clayey backfill [3,16]. However, the effect of uncertainty in soil resistance and operating conditions in upheaval buckling of pipeline and the safety has not been studied to full depth [14].…”
