T-Bar to Spudcan Design Approach in Single-Layer Clays and Calcareous Silts
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 142, Issue 7
Abstract
Difficulties in obtaining high-quality soil samples from offshore sites and heavy involvement of lab testing and engineering judgment have necessitated increasing reliance on in situ penetrometer tests, giving continuous penetration resistance profiles. This paper reports a framework for estimating spudcan penetration resistance directly from continuous resistance profile of a full-flow penetrometer (T-bar) test in single-layer clays and calcareous silts. The framework was validated chiefly against centrifuge test data, supplemented by some reported field data.
