A calculation model for large cylindrical structures is established based on quasi-static analysis on the ABAQUS platform. Through numerical simulation, the stability of large cylindrical structure with different reinforced foundations can be analyzed. The results manifest that the reinforcement effect of the cylindrical structure is not clear when the soil inside the cylinder is reinforced with different burial depths. However, the reinforcement effect of the cylindrical structure becomes obvious when the horizontal and buried depth directions of the soil outside the cylinder are reinforced simultaneously. The reinforcement effect of the large cylindrical structure is roughly the same as that of the soil outside the cylinder when both the inside and outside of the cylinder are reinforced simultaneously. Through comparative analysis, we draw some useful conclusions for practical engineering.
