TECHNICAL FIELD

[0002] In the process of global energy structure transformation towards clean and low-carbon, onshore wind power generation, as a mature and efficient form of renewable energy utilization, its installed capacity continues to grow rapidly. Mountain wind farms, which can fully utilize the wind energy resources of complex terrain, have become an important direction of onshore wind power development. The beam plate type fan foundation (also known as raft type or rib beam type foundation) has been widely used in onshore wind turbine foundation engineering due to its unique structural advantages.

[0003] The foundation is composed of foundation columns, foundation bottom plates, radial main beams and edge secondary beams. Among them, the foundation column is a central cylindrical structure, which is the core component connecting the fan tower; the foundation bottom plate is designed as an octagonal or circular shape as a whole bearing platform to ensure stable bearing of the upper load; the radial main beam is cantilevered from the column, usually 6-8 in number, playing a key role in transmitting the fan load to the surrounding; the edge secondary beam connects the end of the main beam to form a ring structure, further enhancing the stability of the foundation as a whole. Its load transmission path is clear and explicit, that is, the fan load is transmitted to the main beam through the foundation ring, then to the secondary beam through the main beam, and finally to the foundation through the secondary beam. Compared with the traditional gravity type extended foundation, the beam plate type fan foundation can reduce the concrete consumption by about 30%, effectively disperse the load through the beam grid structure, greatly alleviate the problem of cracks caused by hydration heat in the pouring process of mass concrete, and significantly improve the quality and economy of the foundation engineering.
