Abstract: Based on soil slope face grids, a new method is put forward to globally search critical slip surface on slopes. It has preferably utilized both optimization advantages of geometrical and numerical model. Furthermore, its theory is easily intelligible. If assisted by experience analysis on some degree, it will more efficiently get the critical slip surface on soil slope. Two examples are given; the results are both of good convergence and integrity. The method is applicable to some complex soil slopes.

Key words: soil slope, critical surface, geometrical optimization, conjugate gradient method
