三维逆向重构技术在地质教学中的应用——以节理面力学性质教学为例

Application of Three-dimensional Inverse Reconstruction Technology in Geological Teaching:Taking the Teaching of Mechanical Properties of Joint Plane as an Example

讲授岩石结构面的力学性质,是地质专业人才培养的必要环节。然而,传统的教学方式如板书教学、图片展示、动画制作等,都不足以让学生深刻全面地了解结构面在岩石强度中的影响机理。随着计算机技术的发展,三维逆向重构技术使高精度复刻结构面成为可能。为更加充分地满足课程教学需求,使学生能够在实践中对结构面抗剪机理有更加深入的了解,该文将三维光学扫描技术、计算机模型构建技术、3D打印技术用于课堂教学实践,对传统教育方法做进一步改进。

Teaching the mechanical properties of rock structural surfaces is a necessary part of the training of geo⁃logical professionals.However,traditional teaching methods such as blackboard teaching,picture display,and ani⁃mation production are not enough to allow students to deeply and comprehensively understand the influence mechanism of structural surfaces on rock strength.With the development of computer technology,threedimensional reverse reconstruction technology makes it possible to reproduce structural surfaces with high preci⁃sion.In order to fully meet the needs of course teaching and enable students to have a deeper understanding of the shear mechanism of structural surfaces in practice,this paper uses three-dimensional optical scanning technol⁃ogy,computer model construction technology,and 3D printing technology in classroom teaching practice to fur⁃ther improve traditional teaching methods.
