Normally consolidated ground of kaolin clay was made under the acceleration of 50 g. The strength profile of the ground was determined by means of the in-flight vane apparatus and the in-flight cone apparatus. A series of centrifugal tests was carried out to investigate the bearing capacity of shallow foundation on the ground under either vertical or eccentric inclined load.
　Vertical bearing capacity increased with the increase of the footing width. The Davis and Booker's method reasonably explained the effect of strength increase with depth on the bearing capacity. Bearing capacity under inclined load was estimated successfully by the Vaughan et al.'s method. The slip circle method failed to explain the influence on the bearing capacity of load eccentricity, load inclination and strength increase with depth. By the test data, a failure envelope was constructed in the space composed of vertical load component, horizontal load component, and eccentricity.
