Abstract
While various PCPT-based methods for the analysis of consolidation were developed, additional laboratory test is needed to estimate the coefficient of consolidation. In this paper, hyperbolic method using PCPT dissipation curve for the estimation of coefficient of consolidation was proposed. To verify proposed method, field settlement test data and PCPT dissipation test data at same site were collected and analyzed. It is observed that proposed method shows good agreement with measured field settlement data.
