Soil Modulus and Longitudinal Pipeline Stresses
Publication: Transportation Engineering Journal of ASCE
Volume 106, Issue 6
Abstract
Two cases of practical interest in pipeline installation and maintenance are examined: the lifting of a continuous line by a pair of slings and the lifting of a single sling. Theoretical analyses including the effects of foundation flexibility are presented, and the solution of the resulting nonlinear equations by a variant of the Newton method described. Nondimensionalized computer results are given for wide ranges of foundation flexibility and other operating parameters, ready for use in design. It is concluded that the total lifted length is sensitive to foundation modulus, while the sling forces and maximum pipe stress are relatively insensitive. The implications of these results for other pipeline problems, ranging from laying by barge to trenching and profiling, are briefly considered.
