    摘要:

    针对土力学课程教学中关于土工测试这一重要环节存在的问题,自主研发了微型三轴仪作为随堂教具,优化教学模式、加强课堂互动、结合理论与实验教学,以理论知识掌握与实践能力提升为导向,让学生更好地掌握三轴试验的测试方法和流程,进而更直观形象地理解有效应力原理,加深对土力学课程内涵的理解。实践表明,由于该三轴仪体积小、重量轻、便于携带,可模拟实际三轴仪的固结、剪切和控制排水条件等功能,通过该教具在理论课程中进行的演示教学环节,有助于学生掌握不同类型三轴试验的关键操作步骤,直观地体会到有效应力决定土的强度和变形特性这一重要原理,可激发学生学习热情,提升综合实践能力,有效提升了土力学课程中相关内容的教学效果。

    Abstract:

    Aiming at the problem in geotechnical testing, which is the critical part when teaching the course of Soil Mechanics, a portable miniature soil triaxial apparatus was developed in order to optimize teaching mode, strengthen classroom interaction and combine theory and experiment teaching process. Guided by the purpose of learning the theoretical knowledge and improving practical ability, students can better master the testing method and process of the triaxial test, understand the effective stress principle more intuitively and vividly, and enhance the knowledge related in the course of soil mechanics. The practice shows that, due to the small size, light weight and portability of the triaxial apparatus, as well as it can simulate the consolidation, shearing and drainage control functions of the actual triaxial apparatus, the demonstration using it in the theoretical course is helpful for students to master the key operation steps of different types of triaxial tests. Intuitively understanding the important principle that effective stress determines the strength and deformation characteristics of soil can stimulate the learning enthusiasm of students, improve their comprehensive practical ability, and effectively improve the teaching effect of related content in soil mechanics courses.
