论文摘要
风能作为清洁能源已被广泛促进。但是，在风力涡轮机在山区的运行过程中，风力涡轮机基金会出现了许多不稳定现象。为了研究山涡轮机基础的损坏特征，地形对山涡轮机的影响。根据风力涡轮机的复杂机械结构特性，圆形膨胀基础模型的比率为1:10，而风力涡轮机已建立了2MW安装的容量。基础模型由ABAQUS模拟，并分析了土壤压力对随机风负荷下的风力涡轮机基础的影响。了解风力涡轮机基础的脆弱部分。结果表明：（1）在随机风负荷的作用下，锚杆的应变和底部板的接地环很小，不会被破坏；（2）在风载的影响下，在风力涡轮机基础半径半径范围内的污垢很容易受到干扰，但是基础下的核心土壤不受影响。建议应加强风力涡轮机基础半径半径范围内的土壤，以确保基础的安全性和稳定性。
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.
