Abstract
The bearing capacity of sandy ground with one-layer reinforcement was investigated based on the results of centrifuge model tests in the laboratory. The results agreed with those of the conventional model test in gravitational force field: 1) There exists an optimum depth for installing reinforcement at which the reinforcing effect is a maximum; this depth is approximately equal to the width of strip footing, and is independent of the reinforcement width. 2) The qualities of load-settlement and the failure modes vary with the optimum installed depth, and are independent of the reinforcement width. 3) When the reinforcement depth is shallower than the optimum installed depth, although the reinforcing effect increases with reinforcement width, when a certain reinforcement width exceeds, the increase in reinforcing effect lessens.
