8. Square-root – time curve fitting method
The chapter discusses the square-root and log-time curve fitting methods related to pressure increment and consolidation processes in geotechnical engineering. Key steps of the square-root time curve fitting method include plotting the dial reading against the square root of time and determining points of tangency on the curve. Additionally, it explores the time rate of consolidation in laboratory samples compared to field deposits, underscoring the importance of drainage paths in consolidation predictions.
