In the offshore wind farms that have been built in Europe, the rock strata into which the pile foundation enters are mainly sandstone and gravel, and the uniaxial compressive strength of the rock is also relatively low. However, in the geology of some offshore waters in China, there are bedrock which is shallow buried and very hard, and the strength of some weakly weathered rocks can reach more than 130MPa. As a new foundation scheme, the large diameter embedded rock-socketed monopile foundation scheme for offshore wind turbines is very suitable for the bedrock geological conditions in China. For the topography with shallow overburden and strong bedrock, established a "pile - bedrock - grouting material" model, The stress analysis of embedded rock-socketed monopile foundation is carried out, the analysis results show that the maximum stress of the monopile and grouting material satisfy the requirements of extreme cases of wind turbine foundation design，at the same time introduces the selection of filling materials between steel pile and rock hole, grouting technology, as well as the risk and solutions of large-diameter rock-socketed monopile for offshore wind turbines. Therefore, it has some enlightening effect on the design and development of large diameter rock-socketed monopile for offshore wind turbines.
