| 摘 要： | 航道整治河工模型试验,对水流和泥沙运动的相似性要求较严格,试验难度较大。我们在湘江某河段的试验研究中,对模型的比尺设计、床沙分布不一致的模拟、阻力模拟和加沙量的估算等都作了较全面的研究和处理,使问题得到较好地解决,获得了较满意的试验成果。

| Abstract: | In this paper, some experiences in model design with movable bed of sand—gravel reach of xiangjiang river is presented, including model scale design, simulation of bed material and current resistance, and esthnation of bedload transport rate. The result of model teat is in good agreement with the sediment transportation and fluvial process in natural condition. |
