摘要
据田内相似准则设计了一模型网箱,通过试验测量其不同装配、不同流速、不同配重下,网箱表征容积(网箱横截面的投影面积)的变化。结果表明,流速增加使网箱有效容积受到很大损失;增加配重对于改善网箱的变形是有限度的,在网箱底部加装底框可在一定程度上改善网箱的耐流性能,而作者开发的网箱耐流锚泊技术,可以在较大的流速情况下很好地改善网箱的变形,减少网箱的容积损失,提高网箱抗流性能。
The authors designed a model of sea cage based on the Tauchi similarity criteria, and measured the token dimension( the projective area of the cross section) of the sea cage of different assemblages, in currents of different velocity with different bottom weights, thereby they calculated the distortion of acreage of the sea cage. Through analyzing and studying the data of the test, they reached the conclusions that effet dimension would decrease greatly when the current velocity increases, and the distortion of the cage is limited when increasing the bottom weight. They also improved the current resistance of the cage to a certain extent through installing the bottom collar. But the technology of the current resistance mooring system developed by the authors can improve distortion substantially, decrease dimension loss, and increase the capability of current resistance at higher velocities.
