水东水电站为整体式碾压混凝土重力坝，采用宽尾墩－阶梯式坝面－戽池联合消能形式。在新型消能工结构设计方面，用混凝土预制块作为溢流面曲面和阶梯面的结构，用不衬砌和钢筋网喷射混凝土结构代替消力戽池底板和边墙的钢筋混凝土衬砌。工程在运行期经历了近百年一遇的洪水考验，证明了新型消能工结构的优化设计是成功的。 Shuidong hydropower station is an integral RCC gravity dam, with flaring pier - stepped dam surface - Mianchi joint energy dissipation form. In the structure design of new energy dissipater, the concrete prefabricated block is used as the structure of the overflow surface and the step surface, and the non-lining and steel mesh sprayed concrete structure is used instead of the reinforced concrete lining of the floor slab and side wall of the slagging tank. The project experienced a flood test in the recent 100 years in operation, which proves that the optimal design of the new energy dissipater structure is successful.
