7. Determination of coefficient of consolidation (Cv) from laboratory data

The chapter discusses the determination of the coefficient of consolidation (Cv) using three graphical methods: the logarithm of time method, square root of time method, and hyperbola method. It elaborates specifically on the log-time curve fitting approach, detailing the necessary steps for plotting and analyzing consolidation data. The overarching goal is to facilitate understanding of how to interpret laboratory data relevant to soil consolidation and its implications in engineering applications.
