Zusammenfassung:	The invention discloses a thick-plate single-side welding method. The thick-plate single-side welding method comprises the following steps that S100, a single-side Y-shaped beveled edge is arranged at the butt joint position of two steel plates and comprises first beveled edges and second beveled edges which are sequentially arranged, the first beveled edges are close to the front side of the Y-shaped beveled edge, and the second beveled edges are close to the back side of the Y-shaped beveled edge, and the angles of the first beveled edges are greater than the angles of the second beveled edges; S200, after the back side of the Y-shaped beveled edge is coated with a soldering flux, and multiple-wire submerged-arc welding is adopted to perform bottoming welding at the Y-shaped beveled edge; S300, submerged-arc welding is adopted to fill a cover surface layer after forming is completed through bottoming welding. By arranging the Y-shaped beveled edge in a specific shape at the butt joint position of the two st
