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”是本科土木工程专业桥梁工程方向的核心课程之一，但在教学过程中面临课程内容覆盖面广、知识点分散、教学方式单一、实践环节薄弱等现实问题，易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。针对相应问题，从课程知识体系优化、施工现场多媒体资源引入与利用、现场施工信息系统与虚仿真平台的引入等方面开展教学改进探讨，最后以“桥梁支架施工”部分课程内容的教学、课程设计、考核验证了相应教学探索效果。结果表明，梳理知识点主线、突出教学重点、补充现场新技术等能够激发学生的兴趣。线下课堂配合精选现场图片、工程动画讲解知识点，并引入施工现场视频等信息资料强化重点；课后线上MOOC平台预习和复习，并借助虚拟仿真实验平台实践及课程设计，有效提升了教学效果。支架施工课程内容的课程目标达成度分析显示，学生扩大了知识面、扩展了视野并具有主动性、积极性，教学效果达到预期目标，相关教学方法得到验证，并为相近课程教学优化改进提供了参考。

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 who are 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 practical 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 were discussed on the optimization of the curriculum knowledge system, the introduction and utilization of the construction site multimedia resources, the introduction of the site construction information system and the virtual simulation platform. Finally, the corresponding teaching exploration effect was verified based on the teaching, curriculum design and examination of the "bridge support construction" part of the course. The results show that the students' interest can be stimulated by combing the main knowledge points, highlighting the teaching key points and supplementing the new technology on site. In the offline class, on-site pictures and engineering animation are selected to explain knowledge points, and construction site videos and other information materials are introduced to strengthen key points; preview and review after class through online MOOC platform, with the help of virtual simulation experiment platform practice and course design, effectively improve the teaching effect. The analysis of the achievement degree of the course objectives on the scaffold construction course content indicates that the students have expanded their knowledge and vision with initiative and enthusiasm. 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.
