Abstract: Spherical vessel is an important storage equipment in petrochemical industry, so its foundation shall be safe and reliable. On the basis of engineering example, the spherical vessel foundation with different number of legs were modelled and calculated by using SAFE software, and the difference between the horizontal force transmission of arc tie beam and straight tie beam between independent pile caps was discussed. The results show that the horizontal reacting forces of single piles are more balanced when straight tie beam is used. Considering stress characteristics and construction feasibility, straight tie beam is preferably used in the design of independent pile foundations of spherical vessels.

Key words: spherical vessel, independent pile cap, tie beam
