The boundary condition at a pile head has a cosiderable influence on behavior of piles to failure under lateral loading. In this paper, the results of lateral loading tests, which were performed in both conditions of the fixed pile head (no head rotation) and the free pile head (no restraining moment at the pile head), are presented. Furthermore, comparisons are made between the observed pile behavior and that from the analysis previously developed by authors . The analysis is based on the method of incremental lateral displacement, and takes account of shear failure of the soil located in front of the pile and the reduction of pile flexural rigidity at high stress levels. It is found from the comparisons that the theoretical analysis is in fairly satisfactory agreement with the measurements of the pile deflection, bending moment, shear force, soil reaction and so on.
