| 摘 要： | Introduction The stability analysis of soil slopes is usually per-formed by limit equilibrium method (LEM). Gener-ally, the evaluation of soil slope by LEM involvescalculating the safety factor for a given slip surfaceand determining the location of criti…

| Abstract: | A new complex method is presented considering not only the improvement upon the "bad "design point, but also the diversity of the newly generated complex, which is obtained by replacing the "bad "design point with the better design point located at the line between the "bad "design point and the centroid of the remaining design points of the old complex. The new complex method is applied to searching for the critical slip surface of two non-homogeneous soil slopes. The comparison of the results obtained by the new complex method with that by the basic complex method shows that the new complex method is much more likely to find the true critical surface for the randomly generated initial complex. |
