渠底超高法和弯曲导流板法在凤凰水库溢洪道的应用

Application of Canal Bed Superelevation and Curving Guide Wall Method to the Spillway of Fenghuang Reservoir

综合利用了渠底超高法和弯曲导流板法对凤凰水库弯段陡槽的设计,较好地解决了大底坡急流弯道流态的控制问题,可有效地消减冲击波、减小横向水面差、改善弯道水流流态,消能效果明显。实例表明,该设计方法是一种十分有效的工程措施。

The bend steep channel of Fenghuang reservoir is designed by comprehensive utilizing the methods of canal bed superelevation and curving guide wall. It is better to solve the control problem of flow pattern in large foothill jet bend flow, which can effectively eliminate the shock wave, reduce the cross water surface difference, improve the flow pattern of bend and increase the effect of energy dissipation. An example shows that this design method is an efficient engineering measure.
