ABSTRACT
Liquefaction has also been reported in soils containing fine grains, and studies have been conducted on the liquefaction characteristics of fine-grained sands. Evaluation of liquefaction strength using skeleton void ratio and fine-grained void ratio focusing on the skeletal structure of the soil has been studied. However, it is difficult to evaluate the liquefaction strength of sands containing fine grains with different plasticity index based only on the skeleton void ratio and fine fraction void ratio. In this study, fine-grained Toyoura sand with different plasticity index was mixed with the sand to make specimens, and repeated undrained triaxial tests were conducted. The objective of this study is to understand the characteristics of fine-grained sand on liquefaction strength.
