Specifies a practice for the structural design of buried flexible pipelines which rely upon side support to resist vertical loads. The practice applies to pipes with outside diameters equal to or greater than 75 mm, initial ring-bending stiffness equal to or greater than 1250 N/m/m and long-term ring-bending stiffness equal to or greater than 625 N/m/m.

Scope

This Standard sets out a practice for the structural design of buried flexible pipelines which rely primarily upon side support to resist vertical loads without excessive deformation. The interactive pipe/embedment structure is considered only in the transverse direction. Structural performance is predicted in the long-term for pipes in trenches and embankments but not for jacked or bored lines. For the purposes of this Standard, the long-term design basis is 50 years, to take account of creep and other time-dependent effects. The equations used in this Standard apply to pipes with outside diameters equal to or greater than 75 mm, initial ring-bending stiffness equal to or greater than 1250 N/m/m and long-term ring-bending stiffness equal to or greater than 625 N/m/m.

This Standard provides methods and data for calculating the response of a pipe to loadings from –
(a) soil;
(b) superimpositions on the soil; and
(c) both positive and negative internal pressures.
