针对常见的重力式、碟形和拟碟形网箱在不同下潜深度状态下的锚绳受力特性进行了试验研究.试验共设模型4组,分别在纯流、纯波以及波流联合条件下进行.测力通过系缚于锚绳底端的4个拉力传感器获得.试验结果表明水流作用力的大小在很大程度上受网箱结构形式的影响,而在波浪条件下其影响相对较小.重力式网箱的配重形式及下潜形式对网箱的受力具有重要影响.另外,网箱在波流组合条件下的受力并不是纯流及纯波单独作用下的简单叠加.最后,在综合比较网箱价格和性能的前提下,对网箱结构形式的选择进行了一些讨论,并提出若干建议. |

This paper presents experimental studies focusing on the force characteristics comparison of different cage models. A total of four models were used including two Gravity cages, one Sea Station cage and one Quasi-Sea Station cage. Tests were carried out under pure current, pure wave and wave combined with current conditions, respectively. The force data were measured through the transducers attached to the bottom of each mooring line. Analyzed results showed that current-induced loads depended on the cage style greatly but turned out to be relatively weak under wave conditions. The weight configuration and submerging method presented significant effects on the mooring line forces. Results under wave-current conditions were also analyzed revealing that the loads acting on cage models were not the algebraic superposition of those under pure current and pure wave conditions. Comparisons on mooring line forces were also made between different cage models and some conclusions on the selection of the cage style for deep water aquaculture were drawn. |
