封冻河流冰凌挟沙能力的估算

Estimation of Sand Transporting Capacity of the Ice Jam on Frozen River

分析了冰凌输沙的类型和形成机制,不同的类型,不同的规模,会造成不同作用的冰凌输沙运动;对冰凌含沙量、输沙总量、输沙距离的估算方法进行了初步探讨;阐述了研究冰凌输沙的重要意义。

This paper analyzes the types and formation mechanism of ice jam entrainment sediment, thus drawing to a conclusion that ice jam entrainment sediment in various types and scales will lead to different effects of ice jam entrainment sediment movement; Meanwhile the author conducts preliminary exploration on ice jam entrainment sediment concentration, total sediment discharge, sediment transport distance and its estimation method; Finally, the paper elaborates on the significance of making study of the ice jam entrainment sediment.
