The invention provides a suction force calculation method suitable for installation of a single-bucket multi-cabin bucket foundation in sandy soil. The suction force calculation method comprises the following steps: calculating the total frictional resistance of subdivision plates and the frictional resistance Fw of a bucket wall, which are applied to the single-bucket multi-cabin bucket foundation in a suction force sinking stage in the installation process of the single-bucket multi-cabin bucket foundation; barrel wall end resistance Qw and tip and subdivision plate end total resistance borne by the single-barrel multi-cabin barrel type foundation in the suction sinking stage in the installation process are calculated; according to the fact that the sum of all resistances during installation of the single-barrel multi-cabin barrel type foundation during constant-speed sinking in the installation process of the single-barrel multi-cabin barrel type foundation is equal to the penetration force provided by the suction force, the suction force needed by installation of the single-barrel multi-cabin barrel type foundation is calculated by combining the total frictional resistance of the subdivision plate, the frictional resistance Fw of the barrel wall, the total resistance of the subdivision plate end, the resistance Qw of the barrel wall end and the tip; and adjusting the subdivision type of the single-barrel multi-cabin barrel type foundation according to the suction force required by the installation of the single-barrel multi-cabin barrel type foundation. According to the method, the suction force needed in the installation process of the single-barrel multi-cabin barrel type foundation suitable for sandy soil is calculated, and calculation is convenient.
Description
technical field [0001] The invention relates to the technical field of bucket foundations, in particular to a method for calculating the suction required for installation of a single bucket multi-chamber bucket foundation in sandy soil. Background technique [0002] The single-barrel multi-chamber bucket foundation is one of the basic types that has been applied to offshore wind power in recent years. Compared with the single-barrel bucket foundation, the single-barrel multi-chamber bucket foundation can change the suction of the side tank and the middle tank. Realize the control of foundation inclination. In the stage of suction settlement of single-barrel multi-chamber bucket foundation, the sub-chamber plate changes the state of seepage field within the settlement range. In the stage of suction settlement, seepage changes the original stress state of the soil, and with The reduction of the suction of the middle cabin changes the seepage state of the inner wall of the subd...
