Abstract: Based on soil slope face grids,a new method is put forward to globally search critical slip face on slope.It has preferably utilized the optimization advantages of geometrical 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,their results are both of good integrity.It is applicable to some complex soil slopes.
