In recent years, a shift to a recycling-oriented society has been called for, and the promotion of the recycling of waste resources is an urgent task. One of the waste resources is scallop shells, a by-product of fisheries, but they are classified as industrial waste, and their utilization has not progressed due to disposal costs. In this respect, its utilization as a construction material is expected, but the use of lightweight scallop shells (crushed scallop shells) as a substitute for sand is limited, and its utilization is far from sufficient. On the other hand, crushed scallop shells are expected to be applied to pore water pressure dissipation method during earthquakes because of their high permeability by adjusting the particle size, etc. In this study, a laboratory shaking table was used for the experiment.
In this study, we investigated the particle emergence of crushed shells in a columnar drain against excess pore water pressure during earthquakes by laboratory shaking table experiments. As a result, it was found that the crushed shells are effective in dissipating pore water pressure, and that particles do not float in the drain during shaking and that the drain maintains its function.
