摘要
挑流消能是泄水建筑物最常用的消能方式之一。随着高坝工程安全与环境保护对泄洪消能要求的不断提高,新型的鼻坎形式及消能技术日益得到完善。针对高坝泄洪挑流消能工的水流挑距、冲刷、冲击等问题,从理论研究进展对工程实践中面临的问题进行了较为系统的综述,可为水利水电工程消能防冲设计、防洪安全及生态环境保护提供一定的参考。
The ski jump energy dissipation is one of the most commonly used methods of energy dissipation. With the construction of high dams worldwide in recent decades,research problems about new types of buckets emerge. This paper summarizes,discusses and analyzes several typical hot issues in theoretical research and engineering practice,such as jet trajectory,scour and impact,etc. The results are expected to establish a foundation for hydraulic design and even the development of ecological water conservancy.
