河流沉坠式人工生态浮岛固定方式试验

Fixation experiment on ecological floating island of sinking pendant in river

以辽河实际水文资料为基础,在沈阳农业大学水利学院综合试验场内,模拟不同流速水流冲击作用下沉坠式生态浮岛固定方式的稳定特征。结果表明:制作合理的浮岛模型,要始终保持浮岛在水面漂浮,同时减低浮岛在水中的重心;根据不同水流情况,应适当调整浮岛之间的距离,以免发生浮岛相互碰撞,水流速度越大,浮岛之间的距离就越大。研究结果对辽河生态浮岛的布设有着重要的意义。

Based on actual hydrological data, this experiment were conducted at College of Water Resource, Shenyang Agricultural University. This paper studied the stability characteristics of sinking pendant fixation of ecological floating islands under different flow rates of water. Result shows that floating island model should always maintain the island floating in the water and reduce its gravity center. In the condition of different flow rates of water, the distance between the floating islands should be reasonable to avoid collision between different floating islands, and the distance should increase with increased flow rate. The results will supply important basis to the layout of ecological floating island in Liao river.
