The invention discloses a compacted-strand steel wire rope, which is formed by entwisting an inner-layer sub rope and sixteen outer-layer strands; the inner-layer sub rope is formed by entwisting a central strand, six inner-layer strands and twelve secondary outer-layer strands in the same direction; each secondary outer-layer strand comprises six thick strands and six thin strands; the six thick strands are respectively embedded into the concave part of the two corresponding inner-layer strands in a linear contacting manner; the six thin strands are respectively entwisted on the convex part of the corresponding one of the six inner-layer strands in a linear contacting manner; the central strand, the inner-layer strands, the secondary outer-layer strands and the outer-layer strands are respectively formed by entwisting six outer-layer steel wires on one central steel wire; steel wires of the central strand are in point contact; the steel wires among the inner-layer strands, the secondary outer-layer strands and the outer-layer strands are in surface contact. According to the steel wire rope, matching of the steel wires of each strand is reasonably determined, distribution of different strands is optimized, contact area of the steel wires among the strands are further improved, and thereby contact stress of the strands is reduced, and the steel wire rope is good in abrasive resistance. The steel wire rope has the characteristic of being irrational and good in comprehensive performance.
