摘要
太沙基一维渗流固结理论是土力学课程中的重要内容之一,也是教学过程中的难点之一.文章结合弹簧一活塞一水物理模型以及基于Abaqus建立的数学模型辅助教学,对教材中通过单向固结微分方程推导孔隙水压力时空分布规律的教学内容进行重构,利用物理模型和数学模型对教材中的渗流固结过程进行可视化表达.在培养学生数理分析能力的同时,使学生从直观认识和理性分析两个层面理解单向固结理论.
The one-dimensional seepage consolidation theory of Terzaghi is one of the important contents in the study of"soil mechanics"and also one of the difficulties in the teaching process.The article combines the spring piston water physical model and the mathematical model established based on Abaqus to assist teaching,reconstructing the teaching content of deriving the spatiotemporal distribution law of pore water pressure through one-way consolidation differential equation in the textbook,and visualizing the seepage consolidation process in the textbook using physical and mathematical models.While cultivating students'mathematical and analytical abilities,enable them to understand the unidirectional consolidation theory from both intuitive and rational perspectives.
