Abstract:

This paper describes the three-dimensional stability analysis of Carpenter Dam. The presence of keyed construction joints between dam monoliths at Carpenter Dam can significantly affect the distribution of normal stresses at the concrete/rock interface. Therefore, a three-dimensional-beam, finite-element analysis based on the concepts for the trial-load-twist method was performed to accurately model the actual physical behavior of the dam. The vertical stiffness of the foundation rock required by the analysis was determined using rock mass classification techniques. In addition, a procedure for developing modified residual, Mohr-Coulomb failure envelopes that describe the shear strength of the foundation were developed.
