An axial force measuring method comprises the following steps: S1, manufacturing an axial force sensor: respectively arranging n bosses on two end faces of a stress ring to form a beam structure, arranging the bosses on the two end faces in a staggered manner, and installing a strain gauge for detecting deformation to obtain the axial force sensor; s2, calibrating an axial force sensor: performing force calibration on the axial force sensor before the axial force sensor is mounted on an engine for testing, so as to obtain a relationship between a loading force borne by the axial force sensor and the strain of the stress ring; s3, axial force testing: installing the axial force sensor according to the direction of the axial force at the measurement part, and building a measurement system for testing; and S4, measurement and data analysis: processing and analyzing the data according to the axial force test data. The axial force sensor can be used for measuring the axial force of a compressor rotor, a turbine ro
