Q1) The following reading were taken from an increment of vertical stress of in an oedometer test on a saturated clay sample in diameter and thick. Drainage was allowed from the top and bottom boundaries. The water content at the end of loading is . 1) Determine the coefficient of consolidation using the root time method. 2) Compute the hydraulic conductivity of the clay sample.
Expert Answer
use the one-dimensional consolidation theory, which relates the settlement of a soil sample to its coefficient of consolidation and hydraulic conductivity. to calculate the void ratio (e) and the compression index (Cc) of the clay sample using the given water content (w) and specific gravity : is the specific gravity of water (1). e? and e? are the initial and final void ratios, respectively; ?? and ?? are the initial and final effective stresses, respectively.use the root time method to determine the coefficient of consolidation from the given
