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.
Sections
This section covers the methods used to determine the coefficient of consolidation (Cv) from laboratory data, specifically through three graphical procedures.
The Log-time curve fitting method is used to analyze consolidation data by comparing theoretical and experimental curves to determine the coefficient of consolidation.
The coefficient of consolidation is essential for understanding soil behavior under load.
Three graphical methods exist for determining Cv, each with unique approaches and applications.
The log-time curve fitting method involves plotting dial readings against time on a logarithmic scale to evaluate soil consolidation.
Coefficient of Consolidation (Cv)
A parameter that measures the rate at which soil consolidates under applied pressure.
Log-Time Curve Fitting Method
A graphical technique used to determine the coefficient of consolidation by relating dial gauge readings with time on a log scale.
