title = "Assessment of p-y approaches to estimate the lateral response of driven and vibrated piles in sand",
abstract = "Given the popularity of the p-y approach to model laterally loaded piles, this paper evaluates the predictive performance of six existing p-y approaches for piles in sand against a new database of lateral pile tests comprising driven and vibrated piles with a range of aspect ratios. This database includes results from a new series of lateral pile tests designed to assess the effect of installation method on lateral response. It is shown, for driven piles, that the API p-y formulation overestimates lateral stiffness significantly while predictions obtained using CPT-based p-y formulations are reasonable at large lateral pile displacements but underestimate the lateral pile head stiffness of piles with D <0.5 m by about 30%. This conservatism reduces with increasing D and increasing L/D and is such that predicted lateral stiffness values of driven piles in the database with D of 4.3 m and L/D>20 are well predicted by the CPT methods. The new series of lateral tests and other tests reported in the literature indicate that the lateral stiffness of vibrated piles in medium dense and dense sand is between 80% and 90% of that of driven piles.",
