土动力学创新性实验教学中的宏细观思维

Macro-meso perspectives in the innovative experimental teaching of soil dynamics

土动力特性的复杂性和室内外试验对土动力学理论与实践的重要促进作用,决定了土动力学实验教学的重要性。文章分析了目前土动力学实验教学中存在的问题,提出了研究型大学的土动力学实验教学应注重培养学生宏观与细观相结合的创新思维,在实验中提高其宏观调查与问题抽象能力、细观观测与机理揭示能力,正确掌握土的基本动力特性及其工程性状,提高学生解决实际工程问题的能力。

The complexity of dynamic properties of soils and the great positive effects of experiments on the theories and practices of soil dynamics highlight the importance of experimental teaching in this course. We analyzed the problems existing in the current experimental teaching of soil dynamics, and introduced the innovative macro-meso perspectives into this course in research universities, to cultivate students＇ abilities of abstracting scientific problems from macro phenomena and revealing the mechanisms from meso-observations. Then the dynamic properties and engineering behaviors of soils could be properly learned by the students and their capabilities of engineering practice are strengthened.
