Description
Summary:A study aimed at the evaluation of the stability of the Ririe Dam in Idaho was undertaken. The work is to be performed in two phases, the first of which is devoted to two-dimensional (2D) analyses, while the second is concerned with the investigation of the influence of the three-dimensional effects on the overall stability of the dam. This report presents results of Phase I of the program. An extensive number of effective stress stability analyses involving both circular and non-circular failure surfaces were performed using three different methods of stability analyses, namely the modified Bishop, Spencer and MIT methods. Both gravity and earthquake loadings were considered. Circular arc analyses for gravity loading were performed using the computer program STAB3D, whereas the program TSLOPE was utilized for all other analyses.
