摘　　要：通过定床阻力试验,从水力学原理出发,对不同坡度的不同介质床面侵蚀性坡面流试验数据进行分析,初步研究了侵蚀性坡面流流态,得出阻力系数f与雷诺数Re的变化规律,并对他们之间的关系进行分析研究,认为水槽粗糙度对阻力系数存在的显著影响.The test data of overland flow erosion with different bed slope and different media is analyzed in the aspects of water mechanics based on the fixed-bed resistance test. The corrosive nature of overland flow flow pattern is preliminarily studied, while the drag coefficient f and the Reynolds number variation of Re, as well as their relationship, are also discussed in the essay.

关 键 词：坡面流 流态 阻力系数 雷诺数
