摘要
本文系统分析了影响土石过水围堰溢流工况的主要因素 ,提出衡量最不利工况的指标和确定最不利流量的方法 ,为土石过水围堰堰体下游护坡结构及消能防冲设施设计提供了理论依据。通过理论计算结果与模型试验现场观测资料数据对比分析 。
Factors affecting the operating condition of earth rock overtopped cofferdam was systematically analyzed. A method was worked out for measuring the worst operating condition and determining the worst discharge of overtopped cofferdam during construction stage. The results provide theoretical basis and method selecting overflow discharge for the downstream slope protection structure, energy dissipation and reosion control facilities. Comparison with the results of theoretical calculation and model examination shows the method presented herein is reasonable.
