The invention discloses a ground cavity structure applied to a laminated ice-snow sports building, relates to the ground cavity structure, and solves the technical problems of ice field structure destruction caused by the downward cold transfer effect and the cold accumulation problem, high refrigeration energy consumption and high load of an air conditioner in lower auxiliary space in the prior art. The ground cavity structure comprises a cavity, a concrete beam, a support column, fans and a cold storage pool; the cavity is formed in the lower part of the ice surface; the cold storage pool is arranged on one exhaust side in the cavity; and multiple fans are arranged on the other side in the cavity. The ground cavity structure mainly performs vertical isolation on main and auxiliary use space with larger temperature difference, and achieves the effects of saving the refrigeration energy consumption, reducing the load of the air conditioner and maintaining stable temperature environment through such modes as heat transfer stop, cold energy dredging and after cold utilization. The ground cavity structure is applied to the laminated ice-snow sports building.
