对溢流坝段闸墩尾部型式进行了试验研究，特别对翼型宽尾墩引起的挑跌水流作用于河床上的动水压力特性、挑距及冲刷范围随平均流场参数变化的规律作了探讨． 并将定床试验的力学特性与动床试验的冲坑特性之间的关系作了初步研究，给出了冲坑深度与范围的计算方法．
The tail type of spillway gate piers is studied experimentally, especially for the variation of hydrodynamic pressure characteristics, stride distance and scouring range with the mean flow field parameters induced by plunge flaps caused by airfoils flaring pier Exploring. The relationship between the mechanical characteristics of the fixed bed test and the characteristics of the scouring pit in the dynamic bed test was studied. The calculation method of the depth and the range of the scour pit was given.
