  Wind power as clean energy has been widely promoted. However, during the
operation of a wind turbine in a mountainous area, a large number of
instability phenomena appear in the wind turbine foundation. To study the
damage characteristics of a mountain wind turbine foundation, the influence of
topography on a mountain wind turbine is considered. According to the complex
mechanical structure characteristics of the wind turbine, a circular expansion
foundation model have a ratio of 1:10 to the wind turbine which 2MW installed
capacity is established. The foundation model is simulated by the ABAQUS, and
the impact of soil pressure on the wind turbine foundation under random wind
load is analyzed. Understand the fragile parts of the wind turbine foundation.
The results show that :(1) under the action of random wind load, the strain of
the anchor rod, and the ground ring, of the bottom plate is small and will not
be destroyed ;(2) under the influence of wind load, he soil within a 1.5 times
radius range of wind turbine foundation is easily disturbed, but the core soil
below the foundation is unaffected. It is suggested that the soil within a 1.5
times radius range of the wind turbine foundation should be strengthened to
ensure the safety and stability of the foundation.
