与宽尾墩联合使用的台阶面水流压强特性研究

 随着RCC筑坝技术的发展，宽尾墩与台阶面联合消能技术已先后在许多工程中得到应用。通过工程原型与模型试验资料的综合分析，对不同体型及使用条件下，与宽尾墩联合使用的台阶内部压强与总体压强分布规律进行了研究。研究结果表明：台阶内部压强分布规律及台阶总体压强分布规律主要与堰面使用的宽尾墩形式有关，台阶坡比对台阶面总体压强影响幅度较小，台阶高度几乎不产生任何影响。

Skimming Flow Pressure Characteristics on Joint Energy Dissipation of Stepped Dam-face & Flaring Gate Piers

With the development of RCC technology,the joint energy dissipation of flaring gate pier and stepped dam-face has been applied in a lot of hydraulic engineerings.On the basis of the information of experimental test and prototype observation,the paper sums up the law on flow pressure on each step & general steps.As a result,the pressure distributions of each step and entire steps is mainly related to the type of flaring gate pier,the influence of the skimming slope on general pressure is rather small,without...
