Abstract

The coefficient of lateral subgrade reaction of pile is generally given in proportion to -1/2 to -1 power of the pile width. However, since this relationship was obtained from the test results of relatively small diameter piles, the applicability to large diameter piles has not been clarified. The influences of pile width and pile stiffness on lateral subgrade reaction were investigated by centrifugal model tests. When the pile diameter is very large, the lateral subgrade reaction converges to a constant value. The validity was confirmed in comparison with the horizontal loading tests on actual ground.
