Abstract
The strength and deformation characteristics of sandy soil with fines have not been sufficiently clarified, when the fine content ratio is high, but the plastic index is low, or the plastic index is high, but the void ratio is also high. The “ALID” program has been used to simulate the deformation of river levees during earthquakes. In some cases, the results of deformation obtained by analysis and determined in situ in the ground during earthquakes do not coincide entirely, because the properties of such soil with fines are unclear. In the present study, several series of cyclic loading tests and monotonic loading tests after cyclic loading were performed, in order to investigate the strength and deformation characteristics of sandy soil with several plasticity indexes, fine content ratios and void ratios. Consequently, the effects of the properties on the strength and deformation characteristics are clarified using the liquefaction strength and the shear modulus after liquefaction.
