Centrifuge tests on piled raft foundations in sand subjected to vertical load
Résumé
Static centrifuge tests of piled rafts subjected to vertical load were performed in order to examine the interaction of piles-ground-raft. Piles were instrumented with continuous Rayleigh-based optical fiber sensors to measure deformation occurring in the piles.
Optical fiber was also set up in the soil to measure deformation of the ground around the foundation. Two types of piled rafts foundation were tested: a rigid raft (1.5cm thick) and a flexible raft (0.2cm thick). A pile group (without raft touching the ground) was also tested in centrifuge to compare the performance. The optical fiber in the soil showed the extent of the deformation resulting from the loading in the container
