ANALYSIS OF CONSOLIDATION BEHAVIOR OF MICA DAM-CLOSURE

In this closure of the discussion of their original paper, the authors address several issues. They note that direct comparisons are difficult since values of elastic parameters varied according to stress levels. Some approximations could be made using, for example, the average stress in the dam. The assumption of one-dimensional confined compression for the core does not, in their view, control all aspects of the analysis since the analyses of pore pressure dissipation and of stresses and displacements are two dimensional and as such account fully for the asymmetry of the core. Describing construction pore pressure generation by the simplest available function is defended on the grounds that it provides resonable results as long it is not treated as a constrant but varied according to stress level or degree of duration. Also the assumption that total stresses change with changes in external loads provide reasonable results for shut down periods as well as for the case of continuous construction.
