运用沙粒佛汝德相似的原理 ,提出了推移质输沙率的推算公式。并用大型水槽的实验资料和日本国大雪山水库泥沙沉积量资料进行了验证 ,结果表明该方法是可行的。 Based on the similar principle of sand and gravel, this paper puts forward the formula to calculate the sediment transport rate. The experimental data of large flume and sediment deposition data of Da Xue Xue Shan Reservoir in Japan were also validated. The results show that this method is feasible.
