LIQUEFACTION RESISTANCE OF SANDY GROUND SUBJECTED TO OVER-CONSOLIDATION HISTORY
|
´˜^i‰pjF |
Pre-loading method and dewatering method are countermeasures against liquefaction expecting over-consolidation effect. This effect is studied by centrifuge model tests and strain-controlled cyclic tri-axial tests, in which the model ground and the specimen were consolidated through various consolidation histories. The following results are obtained from this study: 1) Over-consolidation effect contributing a settlement reduction is confirmed by centrifuge test. However the effect diminished as the shaking level increased, 2) K 0 -value increase as the OCR increases, but the value decreases after unloading and reloading history, and 3) Over-consolidation effect due to strengthening soil fabric diminished when the specimen is subjected to the cyclic shear strain level over two percent.
