| Research Abstract |
Laboratory experiments and numerical analyses of pile penetration with varying pile penetration methods, pile dimensions, ground conditions were conducted to investigate the bearing mechanism of a pile. Field loading tests on single piles were collected and investigated to evaluate the bearing capacity of actual piles, because it is important to know the bearing capacities of actual piles. Finally we proposed an evaluation method for pile bearing capacity as a function of pile diameter.
