Offshore wind power has the potential to become a renewable energy source for changing gaming regulations, in the context of global high interest in developing low-carbon economy. In a coastal region with dense population, a gigawatt-level offshore wind farm can be quickly established, so that offshore wind power can become one of important technologies for reducing carbon emission in the energy production link in an economic and effective mode. Although offshore wind power starts late, it is rapidly developing all over the world in recent years due to the characteristics of stability of sea wind resources and large power generation capacity. Under the condition that onshore wind power can compete with the traditional power technology in terms of cost, offshore wind power is also drawing wide attention at present, has the characteristic of being highly dependent on technical drive, and has the condition of serving as a core power supply to promote the global low-carbon economic development in the future. At present, the accumulated generated power of the wind power generated by the built and put into operation in China reaches 4.44GW, accounts for 17.95 percent of the total amount of the whole world, and is stable in the third place of the world.
The offshore wind power pile foundation is the key place for supporting the whole offshore wind power machine, the manufacturing cost is about 14% of the whole offshore wind power generation device, and most accidents of the offshore wind power generator are caused by unstable pile foundation. Due to the action of waves and tide, silt around the offshore wind power pile foundation can be flushed and form a flushing pit, and the flushing pit can influence the stability of the pile foundation. In addition, the water flow mixed with silt near the surface of the seabed continuously washes the pile foundation, corrodes and destroys the surface of the pile foundation, and can cause the collapse of the offshore wind turbine unit in serious cases.
