The invention provides a main and auxiliary pile type steel sheet pile structure. The length of each profile steel main pile of the structure is greater than that of a corresponding auxiliary pile of a steel sheet pile, and the ratio of the length of each auxiliary pile of the steel sheet pile to the length of the corresponding profile steel main pile is 1/2-2/3; the distance between centers of each two adjacent profile main piles is 3-6 m, and each auxiliary pile of the steel sheet pile is arranged between the corresponding two adjacent profile steel main piles; flanges of the profile steel main piles are connected with sides of the auxiliary piles of the steel sheet pile through latch fasteners; the profile steel main piles and the auxiliary piles of the steel sheet pile are fixedly connected with cap beams; and the profile steel main piles are connected with anchor piles through steel tie rods. The main and auxiliary pile type steel sheet pile structure has the beneficial effects that the length of each au
