通过模型试验研究了掺气分流墩射流消力塘的压强特性，得出了时均压强和脉动压强沿消力塘的变化关系及最大压强系数随淹没度增大急剧衰减的规律。试验表明，当临界水跃时（淹没度σ＝１），消力塘的脉动压强最大。试验还对脉动压强的功率谱、消力塘下游最小水深进行了研究。该研究可供工程设计时参考。
Through the model test, the pressure characteristics of the jet-flow digester with aerated-pier was studied. The relationship between the mean pressure and the fluctuating pressure along the dipping pond and the law of the maximal pressure coefficient declining sharply with the increase of submergence were obtained. The experimental results show that when the critical water jump (submergence σ = 1), the fluctuating pressure of the digestion pond is the largest. The experiment also studied the power spectrum of pulsatile pressure and the minimum water depth downstream of Xiaotang. This study is available for engineering design reference.
