ANALYSIS OF CONSOLIDATION BEHAVIOR OF MICA DAM--DISCUSSION

While seven different materials were used in the embankment construction described in the paper, the same values for E and V were assumed for both the core and shell materials. However, while V may vary from 0.25 (sandy soil) to 0.5 (saturated clay) E can vary from 40-80 kg/sq cm for medium clay to 500-800 kg/sq cm for dense. Assuming the same value of E for the sand and gravel shell and for the glacial till core can affect the calculated stress distributions and settlements and may possibly explain the finding that settlements calculated using nonlinear triaxial test results overestimated measured settlements by 2.5 to 3.5 times. The central core was founded directly on bedrock while some river overburden deposits were left under shells, thus suggesting the need to account also for the compressibility of the river overburden deposits, while estimating the settlements under construction loads, in the shell portion.
