The invention relates to an indoor dry-wet cycle compression test device and method. The indoor dry-wet cycle compression test device comprises a base arranged in a consolidation box, an outer ring cylinder is arranged on the base, the lower bottom face of the base is hollowed out, an upper permeable stone and a lower permeable stone are arranged in the outer ring cylinder, and a plurality of sets of thin-wall cutting rings which are coaxially arranged in a nested mode are arranged in the space between the two permeable stones; a space enclosed by the thin-wall cutting ring is used for accommodating a prepared sample, and a gland is arranged at the top of the upper permeable stone. The compression part of the consolidometer is designed into a sleeve form and is used for placing an initial soil sample. Different from a traditional consolidation device, the consolidation apparatus box is a drainage device so as to realize dry-wet circulation; the lower permeable stone is not in direct contact with the box, is p
