The invention relates to a factory and dam shared side wall construction joint arrangement area determination method, which comprises the following steps of: establishing a three-dimensional finite element integral model of a hydropower station plant side wall and a drain hole side pier according to a design scheme, obtaining material parameters of concrete and reinforcing steel bars, reading main tensile stress values of fan-shaped reinforcing steel bars and all nodes distributed at intervals in the extension line direction of the fan-shaped reinforcing steel bars, and drawing on-way main tensile stress curves of the steel bars and extension lines of the steel bars, determining demarcation points of the main tensile stress in the attenuation process according to the on-way main tensile stress curves, connecting inflection points to form a demarcation line, and taking a low tensile stress area on one side of the demarcation line as a construction joint allowable arrangement area.
