桥梁施工安全与质量对建造技术的要求越来越高，桥梁建设的高质量发展需要更多一线从事桥梁建造工作的技术人才。桥梁建造作为本科土木工程专业桥梁工程方向的核心课程之一，在教学过程中存在课程内容覆盖面广、知识点分散、教学方式单一、实践环节薄弱等问题，导致教学效果差并影响学生学习专业课程的热情与积极性。结合桥梁建造专业课程建设现状，从课程知识体系优化、施工现场多媒体资源利用、现场施工信息系统与虚仿真平台引入等方面开展教学改进探讨，并从桥梁支架施工部分课程内容的课程设计、考核等验证了教学探索效果。结果表明：通过梳理知识点主线、突出教学重点、补充现场新技术内容等能够激发学生的学习兴趣；通过精选现场图片、以工程动画方式讲解知识点和引入施工现场视频等信息资料突出课程内容重点，借助MOOC和虚拟仿真实验平台进行课程学习和实践设计，有效提升了教学效果。就支架施工课程目标达成度情况分析表明，不仅拓宽了学生的知识面和研究视野，教师教学效果也达到了预期目标，且相关教学方法也得到了验证，可为相近课程的教学优化和改进提供参考。

The requirements of bridge construction safety and quality on construction technology are getting higher and higher, and the development of bridge construction needs more technical talents engaged in bridge construction. Bridge construction is one of the core courses in the bridge engineering direction for undergraduate civil engineering. However, in the teaching process, it is faced with such problems as wide coverage of course content, scattered knowledge points, single teaching methods and weak practices, which can easily lead to poor teaching effect and depressing students’ enthusiasm in learning professional courses. In view of the corresponding problems, the teaching improvements are discussed on the optimization of the curriculum knowledge system, the utilization of the construction site multimedia resources, and the introduction of the site construction information system and the virtual simulation platform. The corresponding teaching exploration effect is verified based on the curriculum design and examination of the bridge support construction part of the course. The results show that students’ interest can be stimulated by combing the main knowledge points, highlighting the teaching key points and supplementing the new technology on site. Through on-site pictures selecting, knowledge points explaining by engineering animation, and construction site videos and other information materials introducing, the key points of the course content are strengthened. Course learning and practice design through MOOC and virtual simulation experiment platform effectively improve the teaching effect. The analysis of the course objectives achievement degree of the bridge support construction course indicates that the students have expanded their knowledge and vision, the teaching effect has reached the expected goal, and the relevant teaching methods have been verified, which provides a reference for the optimization and improvement of similar courses.
