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?
