The invention discloses an all-parameter trackless measurement construction method for a subway catenary, and relates to the technical field of metro construction. The method comprises the steps: S1, obtaining the coordinates of suspension points through the mileages of the suspension points and the distances of the suspension points deviating from the center of a pantograph; S2, conducting surveying, lofting and re-checking, namely importing the coordinates of the suspension points into a total station, setting up the total station by using a CPIII control pile, lofting and marking the suspension points point by point, recording the elevation h of the corresponding suspension points after lofting, and obtaining a measurement angle alpha; and S3, performing all-parameter calculation by adopting the elevation h of the suspension points and the measurement angle alpha to obtain the length of a davit, the installation correction angle of the davit, the production angle of the davit and the installation height of a cantilever on the davit. The method meets the high-precision requirement of a high-speed subway, and can be widely applied to subway catenary trackless measurement construction.
