| Outline of Final Research Achievements |
Static load tests on pile group model (PG) and piled raft model (PR) were carried in model dry sand ground, in order to investigate their behaviours under combination loading. In the static load tests, vertical load tests on single pile, raft alone, PG and PR, and cyclic horizontal load tests on PG and PR with a constant vertical load were carried out. The tests were conducted for PG and PR models with vertical piles alone or with batter piles. It was demonstrated that deformations of PR and PG with batter piles are suppressed compared to those without batter pile in any loading conditions, and that foundation models with batter piles has ductile (tenacious) response.
The static load test results were fairly simulated by three-dimensional FEM analyses in which the mechanical parameter of the sand were estimated from the triaxial tests of the sand.
