| Outline of Final Research Achievements |
Static and dynamic (shaking) load tests on a pile group and a piled raft were carried in a model dry sand ground, in order to investigate behaviours of a model pile group (PG) and a model piled raft (PR). In the static load tests, vertical load tests on a single pile, a raft alone, PG and PR, and cyclic horizontal load tests on PG and PR with a constant vertical load were carried out. Shaking table tests were carried out on PG and PR. It was demonstrated that deformation of PR is suppressed compared to PG in any loading conditions, and that PR has ductile (tenacious) response showing the advantage of PR over PG.
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.
