摘要
为提高大单宽流量阶梯溢洪道的消能和掺气能力,涌现出一大批新型阶梯形式。为掌握新型阶梯溢洪道研究现状,为泄水工程设计管理提供参考,根据大量既有资料,总结了10种新形阶梯型式的研究成果,给出了各阶梯概化结构图,并将新型阶梯的设计成果归纳为五大类。在阶梯应用形式方面,介绍了除传统泄洪消能之外的其他应用形式。研究成果可作为工程实践的参考。
In order to improve the energy dissipation and aeration capacity of stepped spillway with large unit discharge, a large number of new steps have been emerged. To master the research status of the new step forms and provide reference for the design and management of the drainage project, the research results of 10 new step forms were summarized according to a large number of existing data. And then the generalized structure diagram of each step form was given, and the design results of the new steps were summarized into five categories. In terms of step application forms, other application forms besides traditional flood discharge and energy dissipation were introduced. The research results can be used as reference for engineering practice.
