Offshore single pile foundation centralized pile-soil interaction damping calculation method and storage medium
The invention relates to an offshore single pile foundation centralized pile-soil interaction damping calculation method and a storage medium. The calculation method comprises the steps that S1, a soil unit damping ratio-cyclic shear strain curve of a soil layer of a target site is obtained; s2, calculating the pile-soil interaction damping of the single-pile foundation on the p-y spring layer; s3, pile body deformation of the single pile in the depth direction under the target cyclic load amplitude is calculated; s4, according to the pile body displacement response in the S3, the maximum elastic potential energy stored by the soil spring at each p-y spring and the dissipated energy are calculated; s5, calculating strain energy stored in bending deformation of the pile body; s6, integral is carried out in the pile length direction, and energy WD dissipated by all p-y springs and all elastic energy WS are calculated; and S7, calculating the pile-soil interaction global damping ratio of the single-pile foundation. Compared with the prior art, the method has the advantages that the actual soil layer distribution and the damping-strain characteristics of each soil layer can be considered, and the calculation result is more accurate; the method is simple, easy to operate and high in application value.
