In order to further improve the quality of experimental teaching in the college, based on the evaluation criteria of experimental teaching achievements, the status quo and problems of the teaching of soil mechanics experimental courses in the college are analyzed, and the method of finding and filling vacancies is used to find the defects in the design of the experimental teaching system. Based on the previous professional experiments Set up professional basic experiments, revise the experimental performance evaluation plan, discuss the experimental teaching reform and experimental management methods, and construct a series of reforms such as the experimental teaching operating mechanism and experimental teaching performance evaluation system with college characteristics. The results show that the reform of experimental teaching based on the evaluation of experimental class results can better improve the effect of experimental teaching, optimize experimental teaching methods, help to effectively improve students" innovation and practical ability, and at the same time cultivate the quality of independent scientific research work and Competent talents provide some guidance.
