HYDRAULIC MODEL EXPERIMENT ON STABILITY AND SCOUR PREVENTION EFFECT OF FOOT PROTECTION BAG USING COAL ASH MIXED ARTIFICIAL STONE

Abstract

 To expand the uses of coal ash, artificial stone mixed with coal ash has been developed. In this study, the stability and scour prevention effect of foot protection bags using artificial stone mixed with coal ash installed around the foundation of an offshore wind power generation facility was investigated through hydraulic model experiments. As a result, it was confirmed that the foot protection bags are stable in the planned field experiment area. And it was also confirmed that it can be expected to have the same scour prevention effect as in previous research.
