Abstract
AbstractConsolidation parameters are required to support the disposal management of soft soils or mine tailings. The estimation of these parameters from simple correlations using easily measured pr...
Highlights
The geotechnical behavior of soft soils or tailings is very dependent on their hydraulic conductivity–void ratio functions (k-e), which are highly variable, and can be time consuming and/or expensive to obtain from experimental tests: for soft soils these tests can range from months to years
The proposed method relies on an accurate measurement of k at a highvoid ratio, which can be a challenging task for many materials
This paper analyzes correlations for k-e applied to soft soils: clays, clay-based tailings, and dredged soils
Summary
The geotechnical behavior of soft soils or tailings is very dependent on their hydraulic conductivity–void ratio functions (k-e), which are highly variable, and can be time consuming and/or expensive to obtain from experimental tests: for soft soils these tests can range from months to years Estimating these parameters from commonly measured geotechnical properties, such as Atterberg limits or grain size curves, can be advantageous for practitioners, especially when testing candidate amendments to improve the k-e of dredged sediments or tailings. These correlations have been much studied, and recent review papers in the geotechnical literature include Pandian et al (1995), Berilgen et al (2006), Sridharan and Nagaraj (2000), and Chandra Paul and Azam (2013).
