Abstract: Three-dimensional analyses of dams were performed using a computer program developed recently by Wilson (1970). Three dams in V-shaped valleys were analyzed using incremental analysis procedures, in which construction of the dams was simulated in eight steps, and the results were compared with the results of two-dimensional incremental analyses. The comparisons show that the stresses and displacements in the transverse section calculated by plane strain analyses agree closely with the results of three-dimensional analyses of dams in valleys having valley wall slopes as flat as 3:1 or flatter. The values of stress and displacement in the longitudinal section calculated by plane strain analyses agreed closely with the results of three-dimensional analyses for all three valley wall slopes analyzed (1:1, 3:1, and 6:1), but the results of plane stress analyses of the longitudinal section were found to differ significantly from the results of the three-dimensional analyses.
