| Abstract: | The commonly-used methods for slope stability analysis at present were reviewed, the principle of using finite element method in the numerical analysis, and its advantages and disadvantages were all discussed in details. With the Nanfen open-pit Iron Mine as an example, the safety factor of slope stability was obtained using ANSYS software in the numerical simulation analysis followed by using strength reduction method, which can provide a reference in the landslide-prevention design for Nanfen open-pit Iron Mine. |
