基于数值仿真的“隧道工程”课程教改及实践

Teaching Reform and Practice of Tunnel Engineering Course Based on Numerical Simulation

大规模的数值仿真是现代计算力学的主要特征之一,对于深入分析隧道工程中材料破坏本质、工程支护和稳定性评价以及采取相应的预测和防护措施都有很积极的意义。通过将传统隧道工程教学改革为一种新型实验教学模式,使其具有了经济性、拓展性、直观性和综合性等优点。利用高性能服务器对围岩、衬砌和支护结构变形与破裂过程进行数值仿真,不仅具有通用性强、方便灵活、具有可重复性等特点,而且可以通过数值仿真深刻理解许多单凭书本所无法理解的原理和重要观察得来的信息,认识工程结构变形破坏机理,掌握最新的计算方法,对于提高高等学校重要课程的教学水平,培养应用创新型人才具有重要的实践价值。

Large-scale numerical simulation is one of the main features of modern computational mechanics,which is of great significance for in-depth analysis of the nature of material damage in tunnel engineering,engineering support and stability evaluation,and corresponding prediction and protection measures.This research is a new experiment teaching model for the reform of traditional Tunnel Engineering course teaching,which has the advantages of economy,expansibility,intuitiveness and comprehensiveness.Numerical simulation of the deformation and fracture process of surrounding rock,lining and supporting structure by using high-performance server not only has the characteristics of strong versatility,convenience,flexibility and repeatability,but also can deeply understand many things that cannot be achieved by books alone.Understanding the principles and information obtained from important observations,understanding the mechanism of deformation and failure of engineering structures,and mastering the latest calculation methods have important practical value for improving the teaching level of important courses in colleges and universities and cultivating applied innovative talents.
