description The invention discloses a simulation calculation method for the shape of a prestressed steel beam of a railway bridge. The simulation calculation method comprises the following steps: inputting lead point data of the prestressed steel beam; preprocessing the input wire point data of the prestressed steel beam; calculating a local coordinate system of a plane where each traverse point is located; transforming the space coordinates of the traverse points into a local coordinate system; calculating a round chamfer of the lead point; the trimming wire is tangent to the round chamfer; and calculating the linear output result of the prestressed steel beam. According to the method, a traverse point data representation format is defined, and a prestressed steel beam linear contour input method is constructed; a circular curve space coordinate calculation method under a space coordinate system is deduced through a three-dimensional space coordinate system conversion and plane circle chamfer calculation method, so that
