抄録

Normally consolidated clay layers with the undrained strength increasing with depth were successfully made with centrifugal consolidation. Loading tests were conducted on these layers using a rigid strip footing either with a rough or smooth base. The bearing capacities and deformations were measured and upper bound calculations were carried out. The observed bearing capacities are found to be smaller by about 20% for the smooth footing. The bearing capacities normalized by the strength at the surface increases with the increase in the parameter κB/c0, where κ, B and c0 denote the gradient of the increase in strength, footing width and the strength at the surface. The calculated upper bound of the bearing capacities and the failure mechanisms are in reasonable agreement with the observations.
