In recent years,offshore wind power construction has been in full swing,and for the construction of large-diameter single pile foundation,verticality control is a key and also a difficult point.Based on the practical engineering experience,this paper sums up several methods for controlling and measuring the verticality of single pile foundation construction,compares and analyzes the ad-vantages and disadvantages of these methods based on each index,and puts forward the estimation method according to the actual situ-ation,this method can quantitatively evaluate the inclination of steel piles and improve the construction efficiency.Compared with oth-er measurement methods,this method has certain advantages and has certain reference significance for the future large-scale construc-tion of offshore wind power,especially for the verticality control of steel piles during the construction of large-diameter single pile foundation.
