Nonlinear Lateral Pile Deflection Prediction in Sands

摘要: A method has been developed to predict the load-displacement relationship for single piles subjected lateral load, embedded in sands, considering soil nonlinearity using subgrade reaction. This is first systematic study develop load-deflection curves modulus degradation with strain. Based on analysis of 14 full-scale pile-load tests, an empirical equation strain and a range k hmax values, i.e., h at 0.002 1 m (3.28 ft) depth, also proposed. An example problem included demonstrate its use. this method, computed load deflections have compared observed ones those based p - y analysis. shows promise over solutions predicts upper- lower-bound curves, which are valuable guides making informed engineering decisions.
