The invention relates to a spatial multi-dimensional angle control method for an inward-inclined basket arch bridge. The method comprises the following steps of firstly, equal-angle conversion in a main truss connecting direction is carried out, and then equal-angle conversion in a coupling connecting direction is carried out; the equal-angle conversion of the main truss connecting direction and the equal-angle conversion of the coupling connecting direction both take the main truss connecting direction as the length direction of the rod piece and take the length direction as the longitudinal datum line of the rod piece; a straight line perpendicular to the longitudinal datum line is made at the datum line which passes through the original point and is perpendicular to the longitudinal datum line of the rod piece to serve as a transverse datum line, a plane-coordinate system is established with the longitudinal datum line and the transverse datum line, an intersection point serves as a coordinate original poi
