摘　　要：通过对宽尾墩与台阶坝面联合消能工的机理分析,借助工程水力学模型试验,提出一种新型宽尾墩———X型宽尾墩。这种宽尾墩能适应大小流量的变化,具有良好的消能效果,消能率达60%～70%,比常规宽尾墩消能率高5%～10%;产生的射流对消力池底板的最大冲击压力,比常规宽尾墩小30%。因此,X型宽尾墩具有广阔的应用前景。This paper puts forward a new XJXtype flaring gate pier by hydraulic model test for some practical project. The test results show that: this pier can suit the large variable range of discharges; its energy dissipation rate reaches 60%-70%, i.e. 5%-10% higher than that of conventional one; the jet flow pressure acting on the stilling basin can be reduced by 30% in comparison with conventional flaring piers. It may be widely used in hydralic engineering.
