Hydraulic Experiments on Reflection Coefficients for Perforated Wall Caisson with Rock Fill

摘要

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.
