考虑荷载安全裕度的海上风电筒型基础优化反演设计OA北大核心CSTPCD

Based on the concept of load safety margin,the structure optimization inversion design was complemented for one offshore wind turbine supported by bucket foundation in order to reduce the amount of materials and structural cost while ensuring the strength and stability requirements of the structure.Hence,the optimization feedback analysis model and calculation process of offshore wind turbine supported by bucket foundation has been established and the origin bucket foundation was optimization design considering the three safety margin values of 1.10,1.20 and 1.30.It can be seen in the results that the optimized foundation structure still has a better safety reserve after considering the safety margin with the design indicators of the bucket foundation structure,which all can meet the design requirements.This research provides a new idea for the optimization design of offshore wind turbine structure.
