The invention relates to a super-long reinforcement cage hoisting point optimization design and stress calculation method, which belongs to the technical field of foundation underground structure construction, and comprises the following steps: establishing a reinforcement cage hoisting point total coordinate system and two reinforcement cage hoisting point local coordinate systems, which are suitable for four-point hoisting of a reinforcement cage, the method comprises the following steps: carrying out independent stress calculation according to each section of branched rope at the bottoms of two steel wire ropes, calculating the counter force of each hoisting point in combination with the movement track calculation of the bifurcation point of the steel wire ropes, then calculating the bending moment of each hoisting point, and obtaining the point with the minimum absolute value of the maximum positive and negative bending moments according to the algebra, namely the optimal hoisting point. The method has the effects of improving the calculation speed of the bending moment value when the hoisting point of the reinforcement cage rotates and being more accurate.
