基于虚拟现实和3D打印技术的“虚实结合”教学模式在岩土工程课程中的应用探索

Application of a“virtuality-reality”teaching approach in geotechnical engineering based on the visual reality and 3D printing technology

岩土工程课程是一门理论与实践紧密结合的课程,教学内容涉及边坡工程、地下工程、工程岩体等复杂“立体式”结构,传统“平面式”教学的效果往往不佳,学生难以具体且形象地掌握边坡或地下等复杂工程的结构特征。针对这一难题,探索结合虚拟场景和3D打印技术的“虚实结合”教学模式和平台建设,并在课程教学中结合岩土工程实例进行实践应用。实践表明:学生在虚拟场景学习岩土工程的复杂结构,有效解决了学生现场考察面临的成本高、周期长、潜在风险高等不利问题,也更能激发学生的学习兴趣。通过3D打印技术,将虚拟场景和数字模型实体化,能培养学生的实际动手能力和创新思维,提高岩土工程类课程的教学质量。在新工科建设要求背景下,也为学生课外创新性试验等活动提供了平台,有利于教研相长和师生的良性互动。

Geotechnical engineering(GE)is a discipline with a tight combination of theory and practice.It involves many complex stereometric aspects,such as slope engineering,underground engineering,engineering rock mass.Traditional two-dimensional teaching could not give an efficient introduction.The mentioned contents cannot be easily accepted by the students.To solve the problem,a“virtuality-reality”teaching approach and platform combining the virtual reality and 3D printing technique is proposed and practiced.It is found that the proposed teaching method could stimulate the learning interest of students.Students could learn about the complex structures about GE in an easy and safe circumstance,which solves the negative issues such as high cost,long period and potential danger.By using the 3D printing technique,the teaching quality of GE is effectively improved and the practical ability and innovative thinking of students are also cultivated.The proposed teaching approach can also provide a platform for extra-curricular innovative activities with the requirement of new engineering construction,which makes a better collaboration of teaching and scientific research.
