摘要
土的弹塑性模型在《高等土力学》的教学中具有理论深奥抽象、知识晦涩难懂、计算公式复杂等特点,是土的本构关系重要的模型之一。为把抽象难懂的弹塑性模型知识直观形象地展现出来帮助学生们理解,用图形法与Excel表格法进行了授课尝试,同时运用Excel便捷的计算绘图功能计算不同应力路径下土的应力-应变关系,以此提高课堂效率,丰富课堂内容,取得了比较理想的教学效果。
The elastoplastic model of soil has the characteristics of profound and abstract theory, obscure knowledge and complex calculation formula in the teaching of advanced soil mechanics. It is one of the important models of soil constitutive relationship. In order to show the abstract elastoplastic model knowledge intuitively and vividly to help students understand, the teaching attempt is carried out by using the graphic method and excel table method. At the same time, the convenient calculation and drawing function of Excel is used to calculate the stress-strain relationship of soil under different stress paths, so as to improve the classroom teaching efficiency, enrich the classroom content and achieve better teaching effects.
