• In order to investigate the analysis methods for slope stability, stress analysis using finite element method and model experiment using barodynamics equipment were performed for four different models. Slip lines were determined using stress trajectories obtained by the stress analysis and results of triaxial test on material of the model. Magnitude of centrifugal acceleration at which failure of the slope occur was determined theoretically and compared with results of experiment. With regard to models used in this study, failure of the slope always initiates at the lower end of the slope, and a approximately triangular zone up to central part of the slope slides. Such mode of failure greatly differs from the failure on a circular arc which is so far generally assumed in slope stability analysis.
