The invention discloses a heavy vehicle load identification method, which comprises the steps of firstly collecting vehicle actuation deflection data of a target section of a to-be-monitored bridge, processing the vehicle actuation deflection data through a BiLSTM vehicle weight identification model, and obtaining a mapping relation between deflection and vehicle weight according to training learning, so as to invert the actual vehicle weight of a to-be-identified vehicle; meanwhile, video image data of a to-be-recognized vehicle passing through the target section of the to-be-monitored bridge is collected, the video image data is processed through the YOLO target detection model, and the vehicle type of the to-be-recognized vehicle is output; and finally, carrying out information pairing fusion on the actual vehicle weight and the vehicle type of the to-be-identified vehicle output by the BiLSTM vehicle weight identification model and the YOLO target detection model, and jointly outputting the fused informat
