摘　　要：依据定期冲洗式沉沙池水力冲洗的原型观测和模型试验,根据水沙运动特征,提出定期冲洗式沉沙池水力冲洗三阶段冲洗过程及划分,分别给出泄空冲洗、溯源冲洗和沿程冲洗各阶段的计算式和有关参数。Based on the prototype observation and model test made for the periodic-flushing de-silting basin, the process and the division of the three-stage hydraulic flushing are put forward on the basis of the feature of water-sediment movement, and then the calculation formulas and the related parameters for the stages of emptying flushing; retrogressive flushing and the flushing along the basin are given as well.
