This research proposes the slice model that enables to estimate the dynamic fluid pressure due to the tank rocking motion with effects of asymmetrically uplift of the tank bottom plate by solving the velocity potential. In addition, employing an assumption that the tank contents are under the same action of the inertia force induced by the tank rock motion, the fluid contributing to the tank rock motion and rocking-bulging interaction are quantified. This research also develops a static analysis method based on the semi-analytic finite element method and clarifies that accurate calculation of uplift of the tank bottom plate needs all physical quantities related to the dynamical mechanism of the tank rock motion.

本研究提出了切片模型，该模型能够通过求解速度势来估计由于储罐摇摆运动以及储罐底板不对称隆起的影响而产生的动态流体压力。此外，假设储罐内容物受到储罐岩石运动引起的惯性力的相同作用，对储罐岩石运动的流体贡献和摇摆-膨胀相互作用进行了量化。本研究还开发了基于半解析有限元法的静力分析方法，明确了储罐底板隆起的精确计算需要与储罐岩石运动动力机制相关的所有物理量。
