掺气空腔长度是衡量掺气减蚀效果的核心水力指标。针对关于侧掺气空腔长度计算方法的研究成果偏少的现状，通过模型试验和量纲分析，对陡槽上不同坎高和坡度侧掺气坎的空腔特性和射流扩散特性开展了研究，分析侧掺气坎体型参数及来流水力学参数对侧空腔长度的影响，推导出侧空腔长度计算公式，并采用多组实验数据进行了验证。结果表明该公式能较准确地估算侧掺气空腔长度。

The length of aerated cavity is a core hydraulic indicator to measure the effect of aeration. As few research results focusing on the calculation of the length of lateral air cavity, the characteristics of cavity and jet dispersion of lateral aerator with different ridge height and slope formed in chute are investigated based on laboratory model experiments and dimensional analysis, and then the influence of lateral aerator's design value and inlet flow's hydraulics parameters on the length of lateral air cavity are analyzed. The formula for calculating the length of lateral air cavity is finally derived and verified by experimental data. The verifications show that the formula can more accurately estimate the length of lateral air cavity.
