Abstract

The p-y analysis methods are widely used for the displacement design of laterally loaded piles. In clays, the conventional p-y curves are given based on strength parameters such as the undrained shear strength (su) that can be obtained from sampling and laboratory tests. In this study, p-y curve methods based on the cone penetration test (CPT) were presented for both static and cyclic loading conditions. The consideration of continuous soil profiling using CPT is a unique feature of this method introducing the correlation between effective cone resistance and ultimate lateral soil resistance. Lateral displacements of piles were estimated using the CPT-based p-y curve method. The results were compared with the measured data from field load tests. The predicted results showed close matches to the measured results from the field load test.
