摘　　要：“土力学”是高校土木工程的一门核心课程,需要学生理解土的力学行为,进而为土木工程的应用和实践打下基础。而土力学中传统的三轴试验和环剪试验需要花费大量时间,为了提高效率且有效达到“土力学”的教学培养目标,提出将细观数值模拟的离散元方法引入“土力学”教学中。以三轴试验和环剪试验为例,展现了模拟过程,从而发挥细观模拟中颗粒力链组构和变形场可视化的优势,加深学生对受剪切时土体从强度到临界状态演化过程的理解,进而提高学生的学习热情。"Soil mechanics",which is a core course in the major of civil engineering,requires students to understand the mechanical behavior of soil and lays a foundation for practice of civil engineering.Traditional triaxial and ring shear tests in soil mechanics require a significant amount of time.To improve teaching efficiency and achieve the teaching objectives of soil mechanics,the discrete element method on the microscale is introduced.Taking triaxial and ring shear tests as examples,the simulation processes were showed to reveal the advantage of the visualization of particle force chains and deformation field,so as to deepen students'understanding of the evolution process of soil from strength to critical state during shearing,as well as to enhance their learning enthusiasm.
