现阶段，建筑行业的发展呈现出新态势、新格局。经过几十年的高速发展，我国基础建设领域呈现出一定的饱和状态，我国新建筑的建设速度出现逐步减缓的趋势，因此，建筑行业开始逐渐聚焦于对既有建筑的加固修复这一方向上。结合《工程结构全寿命维护》课程实验教学，分析了不同碳纤维增强复合材料（CFRP）加固混凝土梁体系在破坏模式和极限承载力的差异，对采用新型材料开展梁结构抗弯性能实验的新方法和新思路进行了总结，提出了将国家重大需求、工程实践与教学实验融为一体的结构实验教学模式创新改革。该模式作为传统教学的优化和补充，有利于激发学生的实验兴趣和创新思维，培养其发现问题和解决问题，以及理论与工程应用相结合的综合能力。

Currently, the development of the construction industry presents a new situation and pattern. After decades of rapid development, the field of infrastructure construction in China has shown a certain saturation state, and the construction speed of new buildings in China has gradually slowed down. Therefore, the construction industry began to gradually focus on the reinforcement and repair of existing buildings. Combined with the experimental teaching of the course "life cycle maintenance of engineering structures", this paper analyzes the differences in the failure mode and ultimate bearing capacity of concrete beam systems strengthened with different carbon fiber reinforced polymer (CFRP), summarizes the new methods and ideas of using new materials to carry out bending tests of concrete beams, and puts forward the innovative reform of the structural experiment teaching mode, which integrates the national major needs, engineering practice and teaching experiments. As the optimization and supplement of traditional teaching, this mode is conducive to stimulate students' experimental interest and innovative thinking, and cultivate their comprehensive ability to find and solve problems, as well as the combination of theory and engineering application.
