| 摘 要： | 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。

| Abstract: | The paper presents a research on different tail patterns of piers in an overflow dam,and discusses in particular the hydrodynamic characteristics,the distance of water jet scour and the range of erosion area fluctuating with different average flow field parameters when river beds are under the pressure of water jet scour caused by some wing broad tail piers.The paper also covers some primary research on the relationship of movable bed tests,and introduces the method of calculating the erosion depth and area,therefore provides the best pier pattern in construction of river beds against erosion. |
