Geotechnical courses are highly practical. Based on the actual slope treatment engineering and from the perspective of students, 11 experimental tasks are designed. The mouse key operation method commonly used in game software is adopted to conduct interactive independent comprehensive experimental learning under the guidance and prompts of the field simulation system. By selecting a different position and angle to observe and identify site stability, surface and subsurface characteristics of the slope (landslip), according to the characteristics of surface deformation to infer the main direction of sliding, independently designing section line and the survey borehole, drawing borehole histogram, section, and calculating the apparent dip, calculating slope stability and remaining sliding force under various working conditions, simulating and analyzing the arrangement of anti-slide piles and drainage ditch, to enhance students’ cognition and understanding of slope engineering investigation, stability analysis and design process. After the introduction of engineering geology, soil mechanics, slope engineering and other courses in experimental project, the vivid and realistic scenes and shocking effects have attracted and stimulated students’ interest in learning. At the same time, the teaching activity correlation and course interconnection of geotechnical series courses have been realized, and the combination of theoretical teaching and practice has been strengthened.
