摘要
Abstract
The mechanical properties of a new type of gravity-expanded foundation with steel frame structure were studied using numerical simulation methods.The stress of concrete and steel bars,the displacement and inclination rate of the foundation in the numerical simulation results were analyzed.At the same time,the number of steel frames in the new type of wind turbine foundation was studied,and the prestressed steel bars of the foundation were optimized.The research results show that the maximum compressive stress of concrete is only 56%of the compressive strength of concrete.Tension failure is the main failure mode of the foundation.The maximum inclination angle of the wind turbine foundation is much smaller than the upper limit value specified by the standard.Reasonable arrangement of prestressed steel bars in the foundation can effectively reduce the area of concrete tension damage.关键词
