Abstract
In view of the problems of collapsible deformation,differential settlement and insufficient bearing capacity of wind turbine foundations on deep self-weight collapsible loess sites,this study proposes a rational foundation selection and auxiliary design scheme.Taking an onshore wind power project in central Gansu as the engineering background,combined with the geological characteristics of grade Ⅱ to Ⅳ self-weight collapsible loess,this paper compares the technical applicability of foundation treatment measures such as replacement cushion method,dynamic compaction method,pre-soaking method and pile foundation.The bearing performance and economic efficiency of precast pipe piles,conventional bored piles and under-reamed piles are analyzed comparatively.Meanwhile,the supporting design of settlement observation,waterproof and drainage,as well as anti-corrosion protection is completed.The results indicate that the vertical bearing capacity of a single under-reamed pile is 2421.64 kN,superior to precast pipe piles and ordinary bored piles,with a total cost of 1.343 million yuan and prominent economic advantages.The matched settlement monitoring,drainage system and anti-corrosion measures ensure the long-term stable service of wind turbine foundations.It is concluded that under-reamed piles are suitable for wind power projects in deep collapsible loess areas.The combined application of drainage protection and monitoring technology can effectively control loess collapsible risks,which provides a reliable reference for wind energy construction in similar complex geological regions.关键词
