Volumetric Compression Behavior of Fine Grained Soil After Cyclic Loading Process

Abstract

This study investigated the cyclic softening and volumetric compression behavior of fine grained soil under various plasticity index. The volumetric strain was obtained using the drainage test after cyclic loading, and it was observed the effective stress path and stress-strain relationship during cyclic loading process. The volume strain after cyclic loading is different for Liquefied soil and cyclically softened soil. The soil became to liquefaction will cause a large volumetric strain. The main conclusion of this study is that there is a difference in cyclic softening and volumetric compression behavior due to the difference in plasticity index. The non-plastic silt was liquefied and the clay undergone cyclic softening. The volumetric strain after cyclic loading decreases as the plasticity index increases.
