岩体结构面网络仿真系统设计及其教学应用

Design of Simulation System for Discontinuity Network in Rock Mass and Its Application in Teaching

岩体工程中,结构面网络及由其形成的结构体具有复杂性和隐蔽性,无法通过现场观测及物理模型将其展示给学生。为了提高教学效果,设计了岩体结构面网络仿真系统,并给出了系统实现的关键技术。针对复杂结构体识别这一热点难题,提出了网格化方法,使仿真结果更为真实。上述系统可通过激光扫描或参数化两种方式完成岩体模型构建和结构面网络模拟,利用数据可视化及图像处理技术完成仿真。以真实形象的仿真效果将岩体内部的结构面及结构体展示给学生,解决了实践教学中的难题,为理论课程的教学改革提供思路。

In rock mass engineering, the network of discontinuities and the structure body formed by it are complex and hidden, which cannot be presented to students through on-site observation and physical model. In order to enhance the result of teaching, a simulation system of discontinuities network was developed and the key technology of the system is given. Aiming at the hot issue of complex structure body identification, a grid method is proposed to make the simulation results more realistic. The system can simulate the three-dimensional network of the discontinuities by laser scanning or parameterization, and then data visualization and image processing technology were used to complete the display function. The system shows the distribution of the discontinuity in rock mass to students with the real simulation results, which solves the difficult problems in practice teaching and provides ideas for the teaching reform of theoretical courses.
