In this paper, the studies on soil-pile interaction behaviors in saturated sands under static, dynamic and cyclic lateral loads by model testing are described. By comparing with the field test results for piles in soft sandy clay, a formula of p-y curves based on constitutive relationship of soils applicable for both sandy and soft clays is proposed. Good agreements arc obtained in comparison with the field test results performed by other investigators abroad. A p-y hysteresis curve formula based on the modified Masing’s doubling criterion is also proposed, and the results are in satisfactory agreement with field test results.
