A model experiment was performed to study the bending of battered piles due to ground settlement Eight model piles (steel plate 7.5cm×0.9cm×178cm) were installed in the clay layer of 113cm thick as battered piles, and every two piles having the same inclination;　5 °,10°,15°,20°,were hinged at the tops as four coupled piles. While the clay layer were consolidating due to the load of steel shots, the strain of pile surface obtained from bending, the deflection of pile tops and the settlement of ground surface were measured. One of some conclusions obtained this experiment was that the magnitude of maximum bending moment was proportional to the inclination of pile and to the settlement of ground surface.
　Three kinds of calculation were carried out to analize the phenomena. The results calculated by two of them; the elastic analysis by finite element method and the method by Sato et al., coincided approximately with the test results. The best agreement was abtained from the 3rd method, in which the clay layer and the upper sand layer for drainage were assumed to be the Winkler subsoil and the steel shots layer to be the load.
