THREE-DIMENSIONAL FINITE ELEMENT ANALYSES OF DAMS

In this closure to the discussion of the paper, the author agrees that the conclusions regarding the usefulness of plane-strain analyses of the longitudinal section apply only to homogeneous embankments. When the dam is not homogeneous, neither a longitudinal section through the shell nor a longitudinal section through the core gives results representative of the entire embankment, because the movements and stresses in the dam are determined by the properties of both the core and the shell. The movements within the core calculated by a three dimensional analysis will be intermediate between those calculated by a plane-strain analysis performed using the properties of the core and the plane-strain analysis performed using the properties of the shell throught the section. The stresses within the core calculated by a three-dimensional analysis will not correspond to those calculated by a plane-strain analysis of the longitudinal section, no matter what properties are used in the plane-strain analysis, because the effect of upstream-downstream arching is completely absent from the plane strain analyses.
