    摘要:

    目前,海上风电基础冲刷问题难以得到有效解决,需开发一种经济、有效的防冲刷方案。针对仿生草防冲刷方案开展物理模型试验,探讨仿生草尺寸及布置方案对于海上风电单桩基础防冲刷效果的影响。结果表明,综合考虑防冲刷效果及成本的情况下,仿生草高度及布置半径存在一个最优值。仿生草高度为1.5m,仿生草布置半径为1.7倍桩径时,仿生草防冲刷效果较好,且较为经济。

    Abstract:

    At present, the scour problem of foundation for offshore wind turbine is difficult to be solved effectively. It is necessary to develop an economic and effective scour prevention measure. Physical model tests are carried out for the scour prevention measures based on bionic grass, and the influence of bionic grass size and arrangement form on the scour prevention effect of monopile foundation for offshore wind turbine is discussed. The results show that there is an optimal value for the height and arrangement radius of bionic grass considering the scour prevention effect and cost. When the height of bionic grass is 1.5m and the arrangement radius of bionic grass is 1.7 times the pile diameter, the scour prevention effect of bionic grass is better and more economical.
