A Constitutive Equation for Compression Behaviors of Artificially Cemented Composite Geo-Materials
The lightweight soil is an artificially treated soil with air form to reduce the unit weight - therefore making a good backfill material - but is often cement-treated to ensure enough strength. This artificially treated soil has been evolved to be more environment-friendly by using the dredged soft soil and mixing with the bottom ash therefore taking care of by-products of offshore construction and coal production. One of the unique characteristic of this family of Composite Geo-Material (CGM) is that they show drastic strain softening in their stress-strain curves, whose constitutive relations are not properly modeled by casual constitutive models, such as conventional hyperbolic or modified cam-clay model. A set of hyperbolic equations and their parameters are presented based on the uniaxial behavior of CGM materials.
