Provided are: a high-strength thick steel plate having excellent characteristics for preventing the diffusion of brittle cracks; and a method for producing the thick steel plate. The high-strength thick steel plate for construction has an aggregate structure wherein the {311}<011> orientation strength in a rolled surface at the mid-thickness position, and the {110}<001> orientation strength in a rolled surface at a 1/4 thickness position, and, further, a Charpy fracture appearance transition temperature at the 1/4 thickness position are specified according to the desired characteristics for preventing the diffusion of brittle cracks. After hot rolling, rolling under strong pressure is carried out in recrystallization regions and non-recrystallization regions, and the temperature at the plate thickness center subsequently cools.
