Abstract: According to the teaching characteristics of the geotechnical engineering course experiment, a corresponding teaching evaluation system is established. Taking the soil mechanics course experiment as an example, a variety of synthesis algorithm models are designed using the fuzzy mathematics theory to conduct a secondary comprehensive evaluation of the experimental teaching quality. Through the reform and optimization of the curriculum teaching system, setting up a preview assessment mechanism before experimental classes, the implementation of pre-class preparation process, and the addition of virtual simulation experiment projects, students’ participation in experiments has been enhanced, and the quality of experimental teaching has been effectively improved.
