The invention discloses an ecological
wind power pile foundation bottom protection structure and a design method, and belongs to the technical field of
pile foundation bottom protection. The design method is characterized by comprising the steps that S1, basic data are obtained, and the basic data comprise the
wave height H, the
wavelength L, the
water depth D and the foundation width d of a
wind power pile foundation in the 0-10 m coastal near
shore; S2, the relationship among the bottom flow velocity, the
water depth and the block stone
mass is obtained, the bottom flow velocity V is calculated according to the
wave height H, the
wavelength L and the
water depth D; the
mass W of a stabilizing block stone at different bottom flow velocities is calculated, and fitting is carried out on the relationship among the bottom flow velocity V, the water depth D and the block stone
mass W; S3, a block stone protection range is determined; S4, the space between the block stones is filled with graded stones; S5,
zostera marina is fixed to the graded stone; and S6, a reinforcing net is laid on the block stones, and the periphery of the reinforcing net is fixed. According to the technical scheme of the ecological
wind power pile foundation bottom protection structure and the design method, the wind power pile can be prevented from being scoured by
sea waves, meanwhile, the ecological wind power pile foundation bottom protection structure has the advantages of being ecological and
environmentally friendly, and
water quality can be improved and the
ecological environment can be restored while scour is prevented.
