超高海拔高性能纤维混凝土在风电基础工程中的应用研究
摘要
Abstract
Due to the rising demand for clean and renewable energy,wind energy has become a prominent focus as a vital energy source.Nonetheless,the use of traditional concrete encounters obstacles in ultra-high-altitude settings within wind power engineering.To tackle these challenges,this study explores the utilization of high-performance fiber-reinforced concrete in wind power foundation engineering.The mechanical properties and deformation characteristics of wind power foundations constructed with high-performance fiber-reinforced concrete are investigated through numerical simulation analysis.The research findings reveal that as concentrated loads increase,the bearing capacity of wind power foundations gradually improves,albeit at a declining rate of maximum stress.Additionally,the maximum stress is concentrated directly beneath the circular foundation,and the area of maximum stress expands progressively with higher concentrated loads.As the applied concentrated load intensifies,the lateral and vertical displacements of wind power foundations also gradually increase.Following the attainment of the corresponding strength grade by the wind power foundation,on-site tests are performed to evaluate its concrete strength and foundation bearing capacity,which successfully fulfill the requirements stipulated by engineering specifications.关键词
