Abstract

"The main purpose of this study was to predict load-displacement relationship for single piles under lateral loads in sands using subgrade reaction method. The analysis of laterally loaded piles is difficult, requiring solution of a fourth order differential equation.

A method to predict the load-displacement relationship for single piles under lateral loads, embedded in sands, considering soil non-linearity using subgrade reaction approach is proposed. An empirical equation of modulus degradation with strain and a range of khmax values, i.e. kh at 0.002 strain at 10m (32.8ft) depth, has been proposed, based on the statistical analysis of the lateral pile load test data.

An example problem has been solved using the procedure developed to predict load-deflection curve.

Fourteen lateral pile load tests on free headed, long piles were analyzed in this study. There were two steel pipe piles, two H-steel piles, two concrete piles and one timber pile in dense, medium to fine sands, two steel pipe piles in medium sands, four timber piles in loose sands, and one timber pile in very loose to loose sand.

This method is a new step towards finding a realistic solution to a complex problem of predicting load-deflection relationship for piles under lateral loads"--Abstract, page iii.
