| 摘 要： | 在模型试验成果的基础上，分析了跌扩型底流消能工水流流态，并就突扩比对消力池内流态、底板时均动水压力分布、临底流速、近墙流速的影响进行了研究。结果表明，突扩的存在能有效降低消力池边墙水力学指标。该成果可为工程设计提供一定的科学依据。

| Abstract: | Based on the results of model experiments,the flow patterns are analyzed. The expansion ratio influence on flow pattern in baffle basin,distributions of hydrodynamic pressure on the stilling basin,flow velocity and velocity near sidewall are measured. The results show that with the existence of abrupt drop,the lower hydraulics characteristics near sidewall in the basin can be obtained,which may be useful for the engineering design. |
