Description

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 silt contents on the liquefaction suppression behavior of short fibers mixed soil. This study carried out undrained monotonic and cyclic shear test using a short fiber mixed decomposed granite soil with different fine friction contents. As a result, the liquefaction strength of short fiber mixed decomposed granite soil was found to be strongly affected by changes in the skeleton void ratio due to the fine fraction contents.
