Unformatted text preview: 3. Determine void ratio change from each plot, as well as coefficient of consolidation, c v , for each load cycle. Tabulate the data obtained from each plot. 4. Plot e-log σ vc ’ (void ratio versus vertical effective consolidation stress). 5. Determine maximum effective past pressure ( σ p ’). Show the graphical construction on an e-log σ vc ’ graph. Also find Cc and Cs from this graph. Estimate the overconsolidation ratio, OCR, using the current effective vertical stress of 100 kPa. 6. Discuss your results and compare the consolidation test results to published data. 7. Appendices: All calculations. Show ALL formulas if using Excel. Reminders: • Use consistent units and be sure to label all graphs and tables clearly. • Sharing/copying of plots, figures, text, and calculations will not be tolerated and will result in a grade of zero for the lab, along with reporting to the university.
