  The Jinping neutrino experiment is designed to have multiple purposes in the
China Jinping Underground Laboratory. Following the acrylic vessel design
requirements proposal, a structural scheme has been developed and optimized.
Subsequently, the stability of the acrylic shell structure was calculated using
finite element analysis, as well as the load-bearing capacities under various
working conditions. Further, the effects of temperature changes, rope failures,
and Young's modulus of the ropes on the static behavior of the structure were
analyzed. The results indicated that the stress level and structural
displacement of the structure scheme satisfies the design requirements, as well
as the stability of the vessel under compression. Moreover, the stress and
displacement of the acrylic shell satisfies the given working conditions and
temperatures. The structural scheme ensures basic safety if the rope fails.
