FAILURE OF AN OIL STORAGE TANK FOUNDED ON A SENSITIVE MARINE CLAY

The investigation of the failure of an oil storage tank founded on a sensitive, soft-to-firm clay is described. The history of the failure and the geotechnical properties of the clay are reported. Failure occurred during first loading, and an analysis in terms of total stresses has been caried out. The applicability of bearing capacity theories to foundations on this type of clay has been examined, particularly, the propositions that either the bearing capacity factor, or the measured strength of the clay, should be reduced to allow for local shear or progressive failure effects. The results of the analysis indicate that the Skempton-Meyerhof bearing capacity factor for circular loaded areas, N sub C = 6.2, may be used, and that the full measured strength of the clay is mobilized. /Author/
