摘　　要：掺气分流墩射流消力塘是利用掺气分流墩充分掺气、扩散和消力塘的脉动压强随水垫深度增加迅速衰减的特性， 提出的一种新型的消力塘形式。通过试验研究， 得出了这种消力塘的体形参数、水流特性和消力塘的压强特性， 并提出了水力设计的方法。The combination of aerated diversion pier and jet flow stilling pond is a new stilling pond which uses the features of fully aeration and diffusion of aerated diversion pier and the performances that the water pulse pressure in stilling pond will rapidly reduce as the water cushion depth increases Through test and study, the body parameters, flow and pressure characteristics of such stilling pond have been gained and the method of hydraulic design has been put forward
