风机基础钢混组合结构细部损伤分析研究
Study and analysis on detailed damages of steel-concrete composite structure for wind turbine foundation
摘要
Abstract
In order to enhance the safety and economy of the design of the foundation for wind turbine, the gravity foundation for wind turbine and the arrangement of the detailed steel-concrete composite structure for the bearing platform of its pier foundation are studied based on the condition of its foundation structure under the loading with large bending moment through analysis on the effects from the dimensions of the metal ring and the structure sections on the load-beating and damage of the foundation; from which it is pointed out that the damages of steel-concrete composite foundation mainly occur at the concrete near the metal ring and the concrete of the foundation bottom at the loading side, furthermore, the reasonable detailed dimensions of the embedded depth of the metal ring, the upper step height of the foundation, the thickness of the metal ring outside concrete, etc. are put forward as well, so as to ensure rationality of the structure load-bearing. This has a higher engineering guiding significance for the design of the foundation structure for wind turbine.关键词
