The invention discloses an earth pressure balance shield machine cutterhead. The surface of the cutterhead comprises a central area, a facial area and a marginal area, wherein each two-edged serrated cutter arranged on No. 1 to No. 8 cutter seats comprises two cutter bodies and two cutter heads fixedly connected on the cutter bodies, wherein the top face of each cutter head adopts the higher-middle and lower-side structure by gradually raising areas from both sides to the middle parts; the upper part of each side face of the cutter head is an externally expanded inclined face; the middle partof the top face is fixedly connected with a strip-shaped hard alloy, and the top faces of both sides of the strip-shaped hard alloy are fixedly connected with four rows of symmetrically distributed hard alloy column teeth; height differences are respectively formed between the tops of the hard alloy column teeth and the top of the strip-shaped hard alloy; and abrasion proof overlaying welding layers are fixedly connected with the peripheral top faces and the side faces of the strip-shaped hard alloy and the hard alloy column teeth. The cutterhead provided with the structure of the invention can increase advance rate, reduce abrasion and prolong service lives of the cutters, and reduce advancing cost under the circumstance of water-rich sandy cobble strata.
