abstract = "Lateral buckling is an important issue in unburied
high-temperature and high-pressure (HT/HP) subsea
pipelines systems. The imperfection-sleeper method is
one of the most well-known methods used to control
lateral buckling of HT/HP pipelines.
Pipelines-sleeper-seabed numerical models are
established and verified to analyze the buckling
behavior of pipelines using the imperfection-sleeper
method. The influence of six main factors on lateral
buckling behavior is investigated in details based on
the numerical results. Equations of buckling
displacement (buckling displacement is defined by the
final displacement of the middle point of the
pipelines), critical buckling force, and buckling
stress (Mises stress) are proposed using the gene
expression programming technique. These equations show
good accuracy and can be used to assist in the design
of sleepers and assess the compressive and stress
levels of pipelines",
