Abstract
We investigated the deformation of 2 types of reinforced soil wall used a geotextile and geocell (cellure confinement system) by using model experiments. The deformation in this case is from the earth pressures generated in a reinforced soil wall and a geocell soil wall. Each deformation is different. It was proven that the difference of the mechanism of the reinforced soil wall greatly affected the deformation of the reinforced soil wall from this result. As a next step, we estimated a resonant frequency of a geocell soil wall by using a theory of elasticity. However in this case model experiments were not carried out until now. However, these results can be utilized for design of geocell soil wall taking into account earthquake.
