网衣缩结对圆柱形网箱性能影响的初步研究

A probe into the effect of hanging ratio of netting on the properties of cylinder cage

采用网箱模型试验 ,对周长 5 0m、深 8m的HDPE双管圆形重力式网箱 ,通过改变网衣装配方法 ,在不同流速条件下对网箱性能进行了研究。结果表明 ,菱形目装配缩结系数 0 .70 7时网箱的阻力比 0 .6 5时小 ,但在静态时 ,缩结系数 0 .70 7比 0 .6 5时容积损失率大 ;

By the model test in the flume tank, the relationship between the properties of double cylinder gravity cage 50m in perimeter and 8m in depth and Changing mounting ways of netting under different current velocity conditions was studied. The results indicated that the cage resistance under hanging ratio at 0.707 was lower than that at 0.65, while in static state, losing rate of the volume of cage under hanging ratio at 0.707 was bigger than that at 0.65. Mounting ways of belly line have impact on shape of the cage under various water current conditions.
