The invention provides a wheel-rail coupling vertical force detection device for axle counting and an axle counting method. The device comprises a bottom plate, two fastening parts and a fiber grating sensor; the fiber grating sensor at least comprises two stress detection fiber grating sensors, namely a first stress detection fiber grating sensor and a second stress detection fiber grating sensor; the two fastening parts are arranged at the two ends of the bottom plate correspondingly so that the bottom plate can be attached and fixed below the bottom face of the steel rail; the first stress detection fiber grating sensor and the second stress detection fiber grating sensor are arranged on the bottom plate at a certain interval and are used for detecting the wheel-rail coupling vertical force of a steel rail when a wheel passes through. The wheel-rail coupling vertical force detection device for axle counting is high in integration level, convenient to install, stable in structure and high in safety.
