In the development framework of engineering colleges, the cultivation of students’ practical ability has received unprecedented attention. Based on the actual situation of the experimental teaching of the bridge direction of the road and bridge specialty in our school, the targeted teaching experiment reform was carried out, and the comprehensive experiment of the positioning of the crack observation grade steel bar of the reinforced concrete beam was customized, so that the students were fully trained in the application of professional software, experimental hands-on skills, information data analysis and processing, and bridge detection ability. It broadens students’ practical ability and professional vision, and lays a good foundation for future work and employment.
