英文摘要	The numerical manifold method (NMM) has been used to solve geotechnical problems with valuable results. In this paper, a numerical model based on the NMM is proposed to investigate two primary concerns in slope stability analyses, i.e., critical slip surface (CSS) determination and safety factor (Fs) calculation. In our proposed numerical model, the optimization algorithm of MAX-MIN ant colony (MMACOA), which is considered to be an algorithm with the best performance for such optimization problems, will be used to determine CSS. In the process of determining the CSS, the trial safety factor for a trial slip surface is calculated with the vector sum method (VSM) according to the stress field produced by an NMM analysis. Accuracy of the numerical model is validated with three typical examples. The numerical model has great potential in the evaluation of stability of real slopes.
