The invention discloses a method for analyzing stability augmentation lifting force required by transcritical surface sinking of a variable cross-section bucket type foundation, which comprises the following steps of: S1, determining assumed conditions of foundation stability analysis under the condition that the variable cross-section bucket type foundation is submerged in a lower bucket; s2, a stability augmentation lifting force calculation formula needed by the barrel type foundation suitable for adopting the lifting force stability augmentation technology is established; and S3, solving a minimum required stability augmentation lifting force result by adopting an iterative algorithm. The method is used for checking the stability augmentation lifting force needed by stable sinking of the bucket foundation in the transcritical state, and therefore guidance is provided for crane ship selection of the variable cross-section bucket foundation crane ship lifting force stability augmentation technology.
