This paper utilized the finite element limit analysis methods to investigate the stability of slopes of various properties and nature. Specifically, this paper investigated a slope with a soft (weak material) band, a post-quake slope and rock slopes. The conventional Mohr-Coulomb failure criterion and the Hoek-Brown failure criterion were utilized for soil and rock slopes, respectively. The Hoek-Brown failure criterion can be applied directly in the finite element limit analysis methods without the need for conversion to the equivalent Mohr-Coulomb parameters. This paper clearly demonstrates the applicability of the numerical limit analysis methods in both soil and rock slopes. It is also significant to note that the results presented in this paper have two distinct solutions-the upper and lower bound solutions. In addition, the failure mechanisms of the slopes are also shown. Prior assumptions of the failure mechanisms are not required for these finite element limit analysis methods, therefore providing a more realistic understanding of slope failures.
