摘　　要：在高拱坝工程中,泄洪功率及泄流量巨大,泄洪消能安全一直是工程研究的重点。基于淹没冲击射流理论探讨了水垫塘的消能机理,并结合工程实际总结了高拱坝工程中常用的水垫塘型式,以及各自的优缺点。提出并重点介绍了天然水垫塘这一新型消能型式及其在工程中的应用前景。In construction of a high arch dam sate tlood discharging and energy dlsszpatlon have always been taken as a priority in the study of the project due to its huge flood discharging power and flood discharge. The paper makes a discussion on the energy dissipation mechanism based on the submerged jet theory and summarizes various common types of plunge pools used in the construction of high arch dams and their respective advantages and disadvantages according to the construction practice. The paper has proposed and described the natural plunge pool, a new type of energy dissipation and the prospects for its application to the hvdror）ower construction projects.
