摘要
为满足“新工科”人才能力需求,提升学生理论知识、实践与创新能力,从土力学实验的现状出发,梳理现实实验中的不足,提出改革的需求与达成目标。将基于颗粒力学模型的离散元数值技术引入土力学的理论与实验中,实现学生对土体在微观结构的不连续与宏观连续性的全方位理解,提升学生数值模拟水平。通过土力学实验的实体演练,结合线上虚拟仿真实验的自主训练,突破现实实验条件的制约,大幅提升学生动手实践能力。土力学实验的测试结果为离散元数值模拟提供必要的参数支撑,而数值仿真也可补充实验的不足。实验科学与计算科学相辅相成,相互印证,能够有效地深化学生的理论认知,激发学生创新与解决实际工程问题的能力。
In order to meet the demand for“new engineering”talents and enhance students’theoretical knowledge,practice and innovation ability,starting from the status quo of soil mechanics experiment,sorting out the shortcomings in the actual experiment,putting forward the demand for reform and achieving the goal.The discrete element numerical technology based on the particle mechanics model is introduced into the theory and experiment of soil mechanics to realize the students'comprehensive understanding of the discontinuity and macro-continuity of the soil in the microstructure,and improve the students'numerical simulation level.Through physical exercises of soil mechanics tests,combined with independent training of online virtual simulation tests,it breaks through the constraints of actual test conditions and greatly improves students’practical ability.The test results of soil mechanics experiment provide necessary parameter support for discrete element numerical simulation,and numerical simulation can also supplement the deficiencies of the experiment.Experimental science and computational science complement each other and confirm each other,which can effectively deepen students’theoretical cognition and stimulate students'ability to innovate and solve practical engineering problems.
