Floor bearing capacity detection method

The invention relates to a floor bearing capacity detection method, and belongs to the technical field of structure detection. Firstly, according to the frequency corresponding to a first-order formation, a vibration exciter is used for conducting vibration excitation on a floor, a vertical deformation time-history curve of the floor is collected, and floor potential energy change E1 caused by vibration excitation is obtained; then, calculating an equivalent static uniformly distributed load q, and drawing an equivalent static uniformly distributed load-deformation value curve; and finally, determining the bearing capacity of the floor according to the equivalent static uniform load-deformation value curve. According to the method, the dynamic deformation of the excited floor slab is accurately measured by utilizing the sensor, the vibration exciter and a scientific calculation method, the structural bearing capacity of the floor slab can be effectively evaluated, and the floor slab can be rapidly detected in
