摘要:道岔作为实现列车转辙的关键结构，是轨道交通线路的薄弱环节，对服役状态下的道岔科学检测是保障轨道交通安全运营的重要前提。基于“BIM+VR”技术，开设虚实结合的道岔检测技术实验，有效解决了理论教学单一性和现场实践操作空间与时间局限性的问题，极大地激发了学生深入学习专业知识的热情。课程将理论学习、虚拟检测与现场实训有机结合，以立体化的方式培养学生理论知识的学习能力和实践技能的操作水平，有助于引导学生提高创新思维和工程意识，为培养轨道交通创新型人才贡献力量。

Abstract: Turnout is the key structure for train switch. As the weak link of rail transit line, scientific detection of turnout structure during service is an important guarantee to maintain the safe operation of rail transit. Adopting "BIM + VR" technology, this paper proposes a course of the turnout detection technology experiment combining virtual and real was set up, which effectively solves the problems of the singleness of theory teaching and the limitation of operation space and time of field practice and also has greatly stimulated students' enthusiasm of study. The course organically combined theoretical learning, virtual detection and on-site training to cultivate students' learning ability of theoretical knowledge and operation level of practical skills in a three-dimensional way, which is helpful to guide students to improve their innovative thinking and engineering awareness and contribute to the cultivation of innovative talents in track engineering.
