海上风电基础波流作用下新型柔性消能防护措施研究

A new flexible protection of wind turbine foundation scour

海上风电基础局部冲刷对风机安全构成严重影响。结合主动型和被动型防护措施各自的优点,研发了一种波流环境下降低桩周局部冲刷作用的柔性消能防护装置。基于水槽冲刷物理模型试验,研究了防护装置的特性。通过与无防护条件下单圆桩风电基础局部冲刷过程的对比,结果表明,新型柔性消能防护措施可以对圆桩周围的局部冲刷形成有效的防护,同时在防护措施周围未发现二次冲刷现象,部分泥沙在防护措施表面形成了落淤。

The stability of offshore wind farm turbine foundation affacted deeply by scour around piles.A new scour protection,which has the advantages of both flow reducing and bed reinforcing,is researched and developed.Experiments are carried out to estimate the protection performance of new mode against the local scour.Results show that the new scour protection mode can effectively avoid scour hole occurance around pile and itself under wave and current.Some silt also has been found on the surface of new protection,which prove its feature of slow down the current.
