In combination with the instructional contents of anti-slip stability analysis for rock foundation in the course entitled Rock Mechanics provided for undergraduates, the method for calculating the anti-slip stability factor of deep double oblique sliding planes, single oblique sliding plane in rock foundation of gravity dam, as well as shallow horizontal sliding plane in rock foundation of gravity dam is derived based on Coulomb strength criterion by taking rock foundation of gravity dam as an example. The technical engineering measures to enhance the anti-slip stability factor for rock foundation of gravity dam are also discussed based on the formula to calculate the stability factor of gravity dam rock foundation. Both the instructional planning and organization for analyzing the anti-slip stability for rock foundation of gravity dam in the course, which are easy for undergraduate students to understand and master, are still proposed in this paper. Through practice on teaching the proposed method for calculating the anti-slip stability factor for rock foundation of gravity dam to undergraduate students, the expected teaching objectives can be achieved.
