| 英文摘要 | In regard to geotechnical problems, the numerical manifold method (NMM) has many particular advantages over the finite element method (FEM) in many aspects. In the present paper, a numerical model called SRNMM-GPS method is further proposed for slope stability analysis. In the proposed numerical model, a strength-reduction -based NMM (SRNMM) is firstly adopted to predict slope's safety factor and generalized plastic strain (GPS) field that corresponds to the slope's limit equilibrium state. Then, a group of useful points locating within the plastic zone of the slope are determined. With these points, an improved version of least square method is adopted to obtain a rational critical slip surface (CSS), which passes through the point with the maximum value of GPS near the toe of the slope. The proposed SRNMM-GPS method is verified with some typical examples. The proposed method deserves further investigation. |
