To engineer efficient structures offshore, we need to extend our knowledge of soil response. Cyclic loading and high water pressure encountered offshore greatly influence cohesionless soil performance. Silty sand from Frederikshavn wind turbine farm was tested using single diameter height samples with lubricated, smooth boundary piston heads in a Danish triaxial apparatus.
Samples were successfully subjected to loading histories of high complexity. Loading include high strains and stresses, post liquefaction response, transitioning through multiple densities and restoring initial soil properties after long test procedures.
Results suggest the testing method is highly suitable for observing complicated soil response and worth exploring further.
