چکیده انگلیسی
Previous studies of the Kettleman landfill slope failure of 1988 had concluded that the failure, which slid along the underlying liner interfaces with low shearing resistance, occurred as a result of attaining the critical waste fill height. These studies showed, however, some discrepancies in regard to the adopted material strength data as well as the computed factors of safety. Based on the observed sliding-block mechanism, a 3D analysis model was established herein which allowed for variations in material strength mobilization within the sliding mass and at the slip surface. With a careful consideration on the interface strength data, results of forward analysis for the pre-slide slope generally showed better agreement with the field observations. Results of backward analysis for the post-slide slope indicated a consistency in the estimated material strength with the laboratory test data. The current study also showed slightly higher computed 3D factors of safety than the associated 2D values, in both pre-slide and post-slide cases.
