In this study, usability and stability in the caisson filling material were reviewed that copper salg(one million tons per one-year) were produced by smelter. In order to complete these studies, chemical and physical comparing analyses were performed by sea-sand materials as to the materials suitability, After construction, the structural displacement of caisson was measured by the instrument and was examined for stability. As a result of analysis, it was determined that copper slag is eco-friendly, and can be used as recycled alternative to aggregates materials.

In general, the caisson having the perforated wall is used to for the purpose of reducing the wave reflection and wave overtopping. In this study, the hydraulic characteristics (reflection coefficient) of the perforated wall caisson chamber filled with aggregates (rocks) were investigated with hydraulic model tests. When the perforated wall chambers were filled with aggregates, the reflection coefficients would increase. However, it was confirmed that the rock filling method into the perforated wall chamber could secure the stability of the structures and satisfy the hydraulic characteristics at a certain level.
