The invention relates to a service bridge rapid load test method under social vehicle loading, and the method comprises the steps: building a vehicle load spectrum according to historical operation data; establishing a finite element model, and obtaining a calculation influence line and a maximum response according to a test working condition; based on the vehicle load spectrum, calculating an influence line, a maximum response and an impact coefficient, and obtaining a social vehicle loading number; obtaining a bridge actual measurement influence line; enabling the number of the social vehicles on the bridge to be equal to the social vehicle loading number, obtaining lane positions, vehicle weights, axle loads and vehicle distances of the social vehicles, and forming a social vehicle loading fleet matrix; based on the social vehicle loading fleet matrix and a discrete convolution formula, respectively combining the actual measurement influence line and the calculation influence line to obtain a social vehicl
