作为岩土工程专业必修课,土力学的特点有基础性、时代性和实践性。对于目前研究生数量增加的现状,土力学的理论性和专业性又对学习提出了更高的要求,因此有必要在已有课程内容的基础上进行扩展的教学探索。参考在土力学课程教学的经验,联系土力学中的“土的抗剪强度”章节与高等土力学中“土的本构关系”章节,以介绍土的临界状态为重点,补充必要的三轴试验和土的性质相关知识点,以砂土的临界状态分析作为实例,并作以当前热点“微生物加固钙质砂”为主题的报告,介绍了如何扩展土力学知识点,以及如何引入学科前沿。帮助学生理解和巩固基础理论知识,激发和培养学生自主学习的兴趣和能力,为继续深造创造良好的基础条件。

Soil mechanics is basic, timeliness and practical as a required course for geotechnical engineering. With the increase of the number of graduate students, the theoretical and professional nature of soil mechanics has put forward higher requirements for learning, so it is necessary for teaching exploration to expand on the basis of the existing course content. Based on the author"s teaching experience in soil mechanics, the chapter of "shear strength of soil" in soil mechanics and the chapter of "constitutive relation of soil" in advanced soil mechanics were connected. Focusing on introducing the critical state of soil, key points related to triaxial tests and soil properties were necessarily supplemented, and critical state analysis of sand soil was provided as an example. As a current hot issue, information about "microbially induced calcite precipitation" was given as a report. This paper introduced how to expand the study points of soil mechanics and how to introduce the subject frontiers. This helpt students understand and consolidate the basic theoretical knowledge, stimulate and cultivate students" interest and ability in independent learning, and create good basic conditions for further study.
