چکیده

in this paper the factor of safety (fs) and critical line-segments slip surface obtained by the alternating variable local gradient (avlg) optimization method was presented as a new topic in 2d. results revealed that the percentage of reduction in the fs obtained by switching from a circular shape to line segments was higher with the avlg method than other methods. the 2d-avlg optimization method is a new topic for finding critical line-segments slip surface which has been addressed in this paper. in fact, the line-segments slip surface is a flexible slip surface. examples proves the efficiency and precision of the 2d-avlg method for obtaining the line-segments critical slip surface compared to the circular and circular-line slip surfaces.
