摘要
通过试验研究了台阶式溢洪道初始掺气点的位置、在首部台阶上游加掺气挑坎情况下挑坎后的水流流态、空腔长度、通气量。得出了初始掺气点、空腔长度和通气量的确定方法，供工程参考。
The position of the initial air entrainment point and the pattern of flow,the length of the air cavity behind and jet aeration capacity after the aerator was set on the beginning of the step on the stepped spillways have been studied by experimental method o The method for confirming the initial air entrainment point ,the length of the air cavity behind and jet aeration capacity has referencing value for the project.
