What is the typical saturated permeability values for sand, silt and

A sample of San Francisco Bay Mud (a marine silty clay) has an initial void ratio of 1.42, an associated vertical effective stress of 24.5 kPa, and an over-consolidation ratio (OCR) of 8.0. If the recompression index Cr = 0.10 determine the void ratio associated with the pre-consolidation stress. Round your answer to the 3rd decimal place.

A clay layer with two-way drainage reached 75% consolidationin t years. How long would it take for the same clay toconsolidate 75% if it has one-way drainage?

Assume a deep deposit of normally consolidated clay. Which of the following processes or actions would lead to the soil becoming over consolidated (select all options that apply)? A.Construction of a road embankment B.Unprecedented water level drawdown extended over a long period of time C.Traffic loads induced by the presence of trucks on site at times D.Heavy rainfalls raising the original water table at the ground surface E.Deep compaction of the clay deposit
