The invention relates to the technical field of nuclear power overhaul, and particularly discloses a nuclear turbine high-pressure cylinder load measuring and distributing method which comprises the following steps: step 1, mounting a weighing jack at a cat claw on the left front side; step 2, carrying out load measurement on the cat claw on the left front side; 3, a weighing jack at the position of a cat claw on the left front side is dismantled; step 4, performing load measurement on the other three groups of cat claws; and 5, calculating a cat claw load difference value of the high-pressure cylinder. According to the method, the adverse effect of uneven load measurement and distribution of the high-pressure cylinder of the steam turbine can be effectively eliminated, air leakage possibly caused by uneven stress of the steam guide pipe of the steam turbine or large hidden dangers of vibration possibly caused by dynamic and static collision and abrasion are eliminated, and the running reliability of the stea
