Abstract
The 2018 Iburi eastern earthquake caused a traffic obstruction due to bumps of up to 0.3 m caused by sliding deformation due to liquefaction and compressive settlement of the embankment due to seismic motion on the residential road in the Tsukisamu Higashi district of Toyohira-ku, Sapporo. As an effective restraint method for such bumps, the development of countermeasures suitable for residential roads using geocells that can be easily removed and reconstructed is underway. In this paper, a full-scale model test using a large crane is described in detail, which was carried out to obtain the optimum geocell size, non-woven fabric installation method, and optimal compaction method to satisfy the standard value.
