摘要：

The behaviour of a pipeline embedded in a creeping medium is examined. Approximate solutions for a beam in a creeping foundation are developed, and characteristic nondimensional load-displacement relationships are presented. A comparison of these approximate solutions provides upper and lower bound solutions that are consistent with finite element analyses. Furthermore, the simplified solutions can be readily adapted for analyzing the uplift behaviour of shallow pipelines. These solutions can also be used to analyze the creeping behaviour of laterally loaded piles. The results are presented in the form of nondimensional charts that permit hand calculations and rapid verification of the structural design of the pipelines and piles. An approximate three-dimensional solution that accounts for embedment is proposed.
