The invention relates to a combination method for three-dimensional garage groups. The three-dimensional garage groups include: a plurality of single deep well type three-dimensional garages. The single three-dimensional garages are linearly arranged and combined into a single-row three-dimensional garage group through one by one. The single-row three-dimensional garage group is combined into a double-row three-dimensional garage group or a three-row three-dimensional garage group. Two single-row three-dimensional garage groups are staggered by one carport, and a second row B and a first row A are staggered by one carport and are combined into the double-row three-dimensional garage group, or into the three-row three-dimensional garage group. The three-row three-dimensional garage group is composed of A, B and C three rows of single-row three-dimensional garage groups, wherein the second row B and the first row A are staggered by one carport, a third row C and the second row B are staggered by one carport, so that the three-row three-dimensional garage group is formed. The invention has advantages that the garage group has very high capacity, and the area of a basketball court can store 500 vehicles; each three-dimensional garage has an independent collector lane, so that the vehicles can go in and out conveniently and quickly, thereby relieving the pressure for car parking.
