Abstract
Urayasu City had a big damage due to the great Eastern Japan Earthquake in 2011. In the survey results after earthquake, the particle size distribution of the sand boil contained a lot of silt. Therefore, this research is focused on the effect of fine fraction contents on the liquefaction suppression behavior of short fibers mixed stabilized soil. This study carried out unconfined compression test and undrained cyclic shear test of decomposed granite soil with different fine fraction contents mixed a short fiber and cement. As a result, it was cleared that short fiber mixed stabilized soil containing fine particle fraction has an effect of improving liquefaction strength.
