数字岩芯仿真技术在岩石力学课程教学实践和人才培养中的应用

岩石力学是研究岩石在外界因素(如荷载)作用下的变形及破坏特性的学科,是土木、石油工程等专业的一门必修基础课程。传统岩石力学课堂教学中,学生难以对岩石内部变形-破坏过程,以及岩石内部应力分布等现象形成直观的认识。为了改善这一不足,文章提出了一种结合微尺度模型重建及数值仿真的新型课堂教学方法。以某砂岩CT图像重建模型为例,文章详细介绍了利用ANSYS软件开展岩石变形仿真分析的课程应用案例设计。该方法可以实现岩石内部变形-破裂的可视化仿真,从而加深学生对课程内容的理解,激发学生兴趣,有效提高岩石力学课程的教学质量。

Rock mechanics is a discipline that involves in the deformation and failure characteristics of rocks under external factors(such as loads).It is a compulsory course for civil engineering and petroleum engineering,etc.In the traditional classroom teaching,it's difficult for the students to gain an insight on the deformation-crack process,and the distribution of the stress internal the rock.To improve these shortcomings,this paper proposes a new design of classroom teaching using micro-scale reconstructed model and numerical simulation.Taking the reconstructed model from micro-CT image of sandstone as an example,the application cases of rock deformation simulation analysis using ANSYS software are presented detailly.This method can realize the visualized simulation of the internal deformation-crack of rock,which will increase the students'interest in learning,and promote the teaching quality of the rock mechanics course as well.
