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.

    本发明公开了一种变截面桶式基础跨临界面沉放所需增稳吊力分析方法,包括:步骤S1,变截面桶式基础在下桶淹没条件下,确定基础稳定性分析的假设条件;步骤S2,建立适用于采用吊力增稳工艺的桶式基础所需增稳吊力计算公式;步骤S3,并采用迭代算法求解最小所需增稳吊力结果。本发明用于验算桶式基础在跨临界状态下稳定下沉的所需增稳吊力,从而为变截面桶式基础起重船吊力增稳工艺的起重船选择提供指导。
