Due to the effects of bend centrifugal force and abutment wall, many problems in spillway, such as water surface superelevation, transverse shock waves happen. In order to fully embody the influence of added diversion pier and rough-strip on the hydraulic characteristics of the spillway, we studied a 60° bend spillway with a 2.2 ratio of curvature radius to bottom width, and got water depth and flow dynamic axis distribution of typical cross sections of spillway in different experimental schemes. The results indicated that the location of diversion piers and numbers can improve the structure and figure of water surface in spillway to some extent, and the improvement effect of single diversion pier to water surface structure in bend was no better than the combined form of diversion pier and rough-strips. The incidence of largest water surface difference and largest water depth is larger in neighboring upstream and downstream positions of 1/5~2/5 cross section of curve and 4/5 cross section of curve, and the flow dynamic axis of combined scheme of diversion pier and strips was prone to the bend axis. Compared to other energy dissipators of the same type, the combined form of diversion pier and strips position in bend is more economical in saving construction's cost and making construction convenient, which provides theoretical referential evidence for practical construction design.
