Prediction of Pile Shaft Capacity in Tension Based on Some Direct CPT Methods-Vistula Marshland Test Site.

This paper presents different CPT methodologies for the prediction of the pile shaft resistance in tension on the example of three reference screw piles of the Jazowa test site in Poland. The shaft capacity was estimated based on the cone resistance, sleeve friction and CPT excess pore water pressure. Three piles with a diameter of 0.
