摘　　要：为有效达到爆破安全教学目标,提出将数值模拟技术用于爆破安全教学。以爆破动载对既有硐室的影响为例,开展模型实验与数值模拟,将模拟与实验结果相互验证、分析。结果显示:模拟和实验结果具有较高匹配度,二者都能清楚呈现硐室周围的应变分布特征和易破坏部位;与实验只能获取最终结果不同,数值模拟还可展现炸药爆破破岩、爆炸波传播及硐室破坏的全过程。在爆破安全教学中使用数值模拟,既能帮助学生扎实掌握爆破安全知识,还可保证师生们的人身安全、激发学生的学习兴趣和热情。To effectively achieve the teaching objective of blasting safety,numerical simulation technology was applied in blasting safety course teaching.Taking the impact of blasting dynamic load on the existing tunnel as an example,model experiment and numerical simulation were carried out,and the teaching effect of the two methods was analyzed after the mutual verification of simulation and experimental results.The results show that the numerical results have a high matching degree with the experimental results,and both can clearly display the strain distribution characteristics and destructible locations around the tunnel.The blasting experiment can only obtain the final result,but,the numerical simulation can also display the whole process of rock breaking,blasting wave propagation and tunnel failure.The use of numerical simulation in blasting safety course teaching can not only help students grasp the knowledge of blasting safety,but also ensure the personal safety of teachers and students and enhance the learning interest and enthusiasm of students.
