摘要
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中研究的重点。系统总结了冲击射流理论及水垫塘消能机理的研究进展,并对消能区冲刷机理研究现状进行了总结分析。结合工程实际总结了高拱坝工程中常用的水垫塘型式,并分析了各自的工作原理及结构特点。
The security researches of energy dissipation were always the focus in the high arch dams with huge flood discharge and large flood power.The research progress of impinging jet theory and energy dissipation mechanism in water plunge poor was summarized in this article.And then,the study of erosion mechanism in energy dissipation area was discussed.Combined with the engineering practice,the common types of plunge poor were summarized,as well as the working principle and structure characteristics.
