摘　　要：为了研究大藤峡水库冲淤规律及泥沙冲淤对水库库容、水位、航道影响等问题， 对冲泻质与床沙质的划分，首先回顾了既往的床沙质冲泻质划分研究成果，采用钱宁法、自动悬浮理论等方法推求了红水河、郁江上几个测站床沙质冲泻质划分粒径， 进而推求了悬移质泥沙挟沙力公式。The division of bed load and wash load is studied to grasp the rule for wash and deposition of sediment, and the influence of sedimentation to capacity, level of reservoir, channel of navigation. The paper reviews first the resultant of division of bed load and wash load. Then the division grain diameter is inquired by Qian Ning method and automatic suspension theory method for the bed load and wash load in some measuring stations at Hongshuihe River. And then the formula of burning into sand of suspended load is inquired.

关 键 词：床沙质 冲泻质 悬移质挟沙力 水库冲淤
