摘　　要：阶梯式消能工已在广东省溢洪道工程中得到了应用,但目前有关的阶梯式消能工的设计方法尚不够完善。在总结广东省现有的溢洪道陡坡段阶梯式消能工试验研究成果的基础上,阐述了连续的内凹型阶梯和不连续的外凸型阶梯的体型布置方法和消能特性,并在坡度1∶3的陡坡段上进行光滑槽面和外凸型阶梯槽面的消能特性比较。结果表明,溢洪道陡坡段的阶梯式消能工具有消能效果好、可简化下游消能设施等优点。研究成果可供类似的工程研究和设计参考。The stepped energy dissipator has been applied in the spillway project of Guangdong province, but the design method of the stepped energy dissipator is not perfect at present. Based on the summarizing of the test research results of the existing stepped energy dissipator of the spillway in Guangdong province, the size layout and energy dissipation characteristics of the continuous internal concave step and discontinuous outer bulging step are introduced, and the energy dissipation characteristics of the smooth and discontinuous outer bulging step on steep slope section of the gradient 1 ： 3 is compared. The results showed that the stepped energy dissipator of the steep slope section has the advantages of good energy dissipation effect and simplifying the downstream energy dissipation facilities. The research results can be used for reference in the similar engineering research and design.
