Background
After the offshore wind turbine infrastructure is built, the movement of water particles caused by tidal currents and waves can be obviously influenced. Firstly, a horseshoe vortex is formed in front of a fan foundation; secondly, forming vortex at the back flow position of the fan foundation; thirdly, the streamlines shrink on both sides of the fan base. This change in local flow pattern increases the shear stress of the water flow on the bed, resulting in an increase in the sand-carrying capacity of the water flow. If the bed is susceptible to erosion, a scour pit may form locally in the wind turbine foundation, which scour pit may affect the stability of the foundation.
In recent years, pile foundation scour prevention has become an indispensable ring in offshore wind power pile foundation engineering. According to different protection means, the method can be generally divided into stone throwing protection, sand bag protection, bagged concrete protection, solidified soil protection technology and the like, the stone throwing protection and sand bag protection means face resource shortage, the protection effect is poor, secondary scouring and other defects are easily caused, and the bagged concrete scheme is high in price, easily causes environmental pollution and other defects, and also gradually withdraws from offshore wind power pile foundation anti-scouring engineering. The solidified soil protection technology has the advantages of locally available materials, remarkable anti-scouring effect and the like, and the position of the solidified soil protection technology in anti-scouring engineering is increasingly prominent.
