促淤浮帘群的系缆力研究

促淤浮帘群的系缆力大小及其特性的研究对于布置促淤浮帘群的设计及施工有重要的意义。本文通过室内水槽实验,分析了群体中每个浮帘的系缆力随浮帘间距和弗汝德数的变化规律,探明了在定床恒定流条件下浮帘群后横轴回流尺度对浮帘群内系缆力的影响,得到了浮帘群的最大系缆力、各排浮帘系缆力随着间距的增大先增大后减小的结论以及不同尺寸浮帘群的最佳间距范围。

Study on mooring force of suspended flexible curtain group for promotionsedimentation

The study on the mooring force of the suspended flexible curtain（SFC）group and its characteristics is significant for the design and construction of it. Through the relevant in-door flume experiment， the law of the changing of each suspended flexible curtain in the curtain group along with the space in between the curtains and Froude number is analyzed herein， thus the impact from the scale of the transversal return-flow behind the curtain group under the condition of the fix-bed constant flow is proved up， and then the conclusion of that the maximum mooring force of the curtain group and the mooring force of each row of the curtain are to be increased first and then decreased along with the increase of the space in between the curtains as well as the optimal range of the space for the curtain group with various sizes are obtained.
