废旧轮胎浮式防波堤模型试验

Model test of scarp tire floating breakwaters

依据水弹性相似理论设计小比尺的废旧轮胎浮式防波堤模型,该模型试验结果与原型结果吻合较好,验证了废旧轮胎浮式防波堤模型试验所取的相似关系是合理的,试验技术是可行的。研究废旧轮胎浮式防波堤结构衰减波能量的机理,探讨结构相对堤宽、锚链拖地长度、锚链刚度对废旧轮胎浮式防波堤消浪性能及锚链力的影响。在该试验范围内,当堤宽大于0.6倍波长时,透射系数小于0.5,锚链刚度和锚链拖地长度对透射系数的影响不明显。

Based on the hydro-elastic similarity theory,a physical model with small scale for scarp tire floating breakwaters was designed.The model test results agreed with those of the prototypes.The similarity relation for the model tests on scarp tire floating breakwaters was verified to be rational, and the test techniques were feasible.The mechanism of wave energy attenuation of scarp tire floating breakwaters was studied.The influences of relative width of the structure,length and stiffness of the anchor systems on wave attenuation performance and anchor line forces of the scarp tire floating breakwaters were discussed.A conclusion is drawn that within the test range,when the relative width of the breakwaters is larger than 0.6 times the wave length,the transmission coefficient is smaller than 0.5,and the influences of the stiffness and length of the anchor systems on the transmission coefficient are not obvious.
