| Outline of Final Research Achievements |
Effects of diameters of pile and wing near a pile tip on bearing capacity and pull-put resistance are investigated through vertical loading tests. Shaft friction is induced due to earth pressure increment in soil around a pile. In cyclic loading, when the cumulative displacement reaches the yield displacement, the earth pressure increment becomes insignificant accompanying with a significant decrease in shaft friction. In addition, distributions of vertical and horizontal bearing load of piles within a pile group are investigated through horizontal loading tests.
