Zusammenfassung:	A thick low-carbon-equivalent high-toughness wear-resistant steel plate and a manufacturing method therefor, relating to the technical field of steel production. The steel plate comprises the following chemical components by mass percentage: C: 0.15%-0.17%, Si: 0.20%-0.40%, Mn: 0.90%-1.10%, P≤0.012%, S≤0.002%, Cr: 0.60%-0.80%, Mo: 0.30%-0.50%, Ni: 0.50%-0.70%, Ti: 0.008%-0.020%, Nb≤0.050%, V≤0.020%, B: 0.0010%-0.0020%, Alt: 0.04%-0.07%, N≤0.0040%, H≤0.0002%, with the balance being Fe and inevitable impurities. Ceq≤0.60%, and Pcm≤0.32%. The mechanical properties of the steel plate are as follows: the yield strength is greater than or equal to 1000 MPa, the tensile strength is greater than or equal to 1100 MPa, the elongation is greater than or equal to 10%, the surface Brinell hardness is greater than 400 HB, the core Brinell hardness is greater than 330 HB, the -40℃
