The course of soil mechanics not only contains in-depth scientific principles, but also closely relates to daily life and engineering practice. It is important to combine the teaching with engineering practice. In fact, on the premise of being good at observation and association, teaching staff can extract interesting things from daily life through observation, so as to activate the atmosphere and improve students’ concentration. And through the development of teaching aids, the complex mechanism can be demonstrated concretely, so as to improve the teaching efficiency. We should take advantage of the natural advantages of the close connection between soil mechanics and ideological and political education, and integrate historical relics, major events and major projects into the classroom. Finally, it can achieve the teaching effect of relaxed and interesting, concrete demonstration and integration into ideological and political education.
