This work is an interactive teaching program that uses virtual reality augmented technology to teach. Let students take the common prevention and control measures of landslide as the basic practical skills, through the practice of virtual reality can be personally on the scene of the lattice structure anchoring project, the abstract, complex treatment engineering example theoretical knowledge into the image, vivid, concrete practical experience. 3D Studio Max and Cinema 4D are used for model making, and the model used on the site is restored one by one to ensure similar on-site investigation of the Three Gorges reservoir area and record the experience of on-site operation. At the same time, the Photoshop is used to make maps for the model, the whole interface design and the Unity3D game engine are used to simulate the operation of the real scene. The operation and process of on-site construction are restored one by one, and the improvement is continuously optimized. This ensures that under the safety of the user's environment, it can also provide users with vivid and interesting knowledge system. Not only can enhance the learning experience, but also improve the learning effect. After the system is mature, it can be applied to various science and technology museums, museums and universities, with a wide range of applications and huge market potential.
