• A multi-planar sliding surface method, a limit equilibrium method for analyzing slope stability, was developed from a tri-planar sliding surface method. In this analysis, a mountain slope is assumed to be covered with many rectangular blocks of potential failure layers. Application of the multi-planar method showed that the site of the most dangerous mass (which shows the smallest safety factor value) appeared at or in sites where failures already had occurred. Analysis that employed the same shear strength for 24-hour submerged samples showed that the safety factors for failed slopes were smaller than those for nonfailed slopes.
