This paper introduces the main style and material of regulating structures, and analyzes the type and reason of erosion of regulating structures in Chuanjiang river. On this basis, depending on the channel regulation project of Xuhu reach (Yibin to Luzhou) at the Yangtze River Artery, this paper proposes to carry out a research on the experimental investigation for the use of accropodes for the dam armour. The result shows that the structure has a good effect of stability and energy dissipation, and thus shall be widely used in channel regulating structures.
