The invention discloses a normalized extra-thick plate with high strength and toughness and the thickness of 150mm and a method for manufacturing the normalized extra-thick plate, and belongs to the field of technologies for manufacturing extra-thick plates. The method mainly includes controlling technological parameters in steps of molten steel smelting, plate slab casting, steel plate rolling, steel plate normalizing treatment, cooling and the like. The normalized extra-thick plate and the method have the advantages that reasonable composition systems and optimized 'control-rolling, normalizing and weak water cooling' technologies are designed, accordingly, the steel plate is excellent in comprehensive mechanical property and good in impact toughness at the temperatures of minus 40 DEG C and minus 60 DEG C, different positions of the steel plate in the thickness direction are low and stable in mechanical property difference, requirements of Q460-level extra-thick steel plates with the thicknesses of 150mm on the strength and the impact toughness can be completely met, and the normalized extra-thick plate and the method have excellent application prospects in the field of steel for engineering structures.
