Abstract
Understanding the compressive behavior of reconstituted clays plays the central role for many infrastructures that built in coastal areas. This paper presents a comprehensive approach for the determination of intrinsic compressibility of reconstituted clays with different initial water contents. Following the conventional practice of geotechnical engineering, the compression curve is expressed by two straight lines in the bilogarithmic space, with a remoulded yield stress being introduced to distinguish the two linear segments. On the basis of extensive experimental data from literature, parameters for the description of two linear segments can be obtained through a pair of functions of initial void ratio and void ratio at liquid limit. Then, a comprehensive equation for intrinsic compressibility is formulated to replace empirical approaches based on curve fitting. The proposed equation contains a small number of parameters, which can be obtained through consolidometer tests. This approach is validated through comparison between model predictions and experimental results for remoulded clays under a wide range of effective stresses and initial water contents.
