Selection of wind turbine foundation PHC pipe-piled in electric yard in aeolian sand

This paper briefly introduces topography and the geological characteristics in a wind turbine yard project in the thick aeoline sand,and preliminarily analyzes pile type selection of foundation plans of the wind turbine foundation.Through comparing the characteristic,cost performance good,application scope,construction scheme and correlative parameter of different pile types,the paper determines the pile type of the wind turbine foundation.At the same time,the paper finally presents the advantages of the prestressed concrete pipe-piled in the wind turbine foundation in the aeoline sand,the problems which may occur in the construction process and the application through the comparison.
