The cultivation of students’ comprehensive quality is an important goal of educational reform. The classroom teaching in engineering universities should not only improve students’ theoretical knowledge level and cultivate their professional skills, but also appropriately infiltrate values, professional ethics, and professional legal concepts into every link of teaching. Taking the soil mechanics course as an example, in combination with local engineering projects, students are encouraged to find theoretical support in engineering phenomena by selecting cases around them, and apply the theoretical knowledge of soil mechanics to the process of solving practical engineering problems, so as to deeply understand the theoretical basis of assumptions made in relevant calculation methods and understand the essential relationship between engineering problems and scientific problems. Give full play to teachers’ scientific research advantages, introduce numerical simulation methods into the classroom, make the complex soil transparent, observe the development process of internal stress, deformation and seepage, and enhance the intuitive and vivid theoretical knowledge. By establishing an appropriate numerical analysis model, we can strengthen the connection between knowledge points in the textbook, so that we can not only know the results, but also know the causes, in the case teaching participated by students, explore the ideological and political elements in the classroom, cultivate students’ sense of professional pride, social responsibility and scientific and realistic spirit, and cultivate comprehensive talents with high professional quality, strong practical ability and responsibility from various aspects.
