- Please help me understand the following soil mechanics questions and the outcomes I have noticed from my lab experiment. For context, I performed a one-dimensional consolidation test, also called oedometer test. These questions are so that I can better understand the theory behind the lab I did, and will NOT be used in an assessment. 1. In comparing the c_v values obtained from the Root-time and the Log-time methods. Should I expect these two values to be similar or to be significantly different? Please provide specific reason(s) as to why or why not. 2. What are two factors that could have affected the value of preconsolidation pressure (σ_c^' ) inferred from the Void Ratio vs. Effective Vertical Stress graph?arrow_forward2- The following are the results of four drained direct shear tests on undisturbed normally consolidated clay samples having a diameter of 2.0 inches and height of 1.0 inch. a) Draw a graph on excel for shear stress at failure against the normal stress and determine the drained angle of friction from the graph. b) If a drained triaxial test is conducted on the same soil with a chamber confining pressure of 4,344 lb/ft², what would be the deviator stress at failure? c) For part b, what is the inclination of the failure plane with the major principal plane?

- Sand cone equipment is used to perform a field density test on a compacted earth fill. • Soil sample dug from the test hole = 20.60 N • Dry weight of soil sample = 17.92 N Ottawa sand used to fill the hole weighs 16.05 N and is known to have a density of 15.74 kN/m3. Determine the in-place dry density of the tested soil. Answer:arrow_forwardThe following data has been obtained from a standard Proctor test conducted on a silty clay soil. The maximum dry unit weight = 17.5 kN/m³; Optimum water content = 12.5% The construction specifications require a relative compaction of 95% and field compaction water content to be within ±2% if the optimum. A sand cone test was performed to measure the dry unit weight and water content achieved during the field compaction operation. The volume of the test hole has been already been calculated from the sand cone data Volume of test hole = 1.5x10-3 m³.
