| Description |
This was a Joint Industry Project
(JIP) with the U.S. Army Corps of Engineers,
Waterways Experimental Station (WES) and Texas A&M University; to study parameter
trends and phenomenological aspects of the moving soil sediment/pipe interaction problem.
Research consisted of characterizing the viscous drag of soft soils on embedded pipelines.
Equations were developed for soft soil. The soil pipeline interaction was validated with
model experiments at Texas A&M University. Based on these results a computer program
was developed that can evaluate pipeline trajectory and pipe stress information for a more
thorough design review. |
| Progress |
Completed. Work consisted of three
items;
1) development of a revised viscoelastic model for soft
marine sediments, based on effective stress formulation,
2) modifications to the large-scale simple shear apparatus
to permit pore pressure measurement,
3) revision to the pressurized pipe-drag device to increase
its operating pressure range.
A final report for the Phase II effort has been prepared,
reviewed, and distributed. |
