Failure Envelopes for Combined Loading of Skirted Foundations in Layered Deposits

A robust and integrated interpretation of soil data from field investigations can provide valuable insights into the important role deterioration following installation suction caissons. Therefore, a experiment was conducted at site in Frederikshavn to simulate laterally loaded caisson layered profile. The performed validate our modeling approach systematically analyze predictive capabilities three classes numerical predictions (Classes A, A1, C). Class A1 prediction focused primarily on trajectory rotation center capacity existing failure criteria predict bearing strength shallow foundations under combined loading, despite differences stress conditions, foundation geometries, weakening due effect. On other hand, carried out based wished-in-place conditions. Failure envelopes within C were adopted be scaled by pure capacities (given intersections with axes). Subsequently, appropriateness identical examined here employing three-dimensional finite-element analyses presence parabolic variations stiffness depth. An alternative macroelement model varying surface parameters also represented, which enables skirted predicted for wide range embedment ratios sand inhomogeneities.
