摘　　要：圆中环沉沙排沙池泥沙水力计算方法的研究不仅便于了解其它类似沉沙池的水力特性,而且还能依据该方法推出满足条件的沉沙池尺寸。按照沉沙池的设计规范进行水力计算,包括泥沙沉速计算、泥沙沉降率计算及泥沙起动计算,并与模型试验的研究成果进行比较分析。结果显示:泥沙各粒径组沉降率的计算值与试验值偏差不大;泥沙起动流速的计算也为沉沙池结构设计提供了有力依据,同时再次验证圆中环沉沙排沙池设置的合理性,并进一步研究沉沙池的优化设计,为以后类似沉沙池设计提供了可靠方法。This paper analyzed the hydraulic calculation method of the circular-ring desilting and sediment ejection basin,it is not only convenient to understand the hydraulic characteristics of other similar basin,but also to deduce the size of the other eligible desilting and sediment ejection basin.According to the design specifications of settling basin for hydraulic calculations,it calculated the sediment settling velocity,sediment and silt sedimentation rate first,the comparative analysis and model were also tested.The results show that： the calculated and experimental values of the deviation of sediment each particle sedimentation has little difference; incipient velocity is also calculated for settling basin structure which could provide basis for structure design,but once again proven circle ring settling desilting pool is reasonable,and could provide a reliable methods for similar settling basin design in the future.
