Evaluation of Erodibility on Clayey Ground and DCM Hardening Mixture in West Coast

The purpose of this study is to evaluate the erosion characteristic on foundation part (clay and sand grounds and deep cement mixing (DCM) of coastal construction in the West Coast region. For erosion evaluation tests, clay and sand samples were prepared through consolidation and compaction, in the case of DCM sample was prepared by mixing the blast furnace cement considering real condition in the construction field. The erosion rate and shear stress were quantified using EFA (Erosion Function Apparatus). As result, the critical velocity and critical shear stress were calculated and its erodibility was evaluated by erodibility chart.
