Numerical simulation of wet deposited Phosphogypsum embankment resting on dry deposited one

What is it about?

The storage of phosphogypsum waste constitutes a very challenging issue to the environment. storage of Two types of storage, the dry method and the wet method, are of current usage. in the Tunisian context, the optimisation of landfills led to adopt the wet method on an existing deposit by the dry method. It is with interest to predict the numerical behavior of this composite landfill in the absence of follow up programme with monitoring devices. The paper compares the predictions by Plaxis 2D and Midas 3D codes of the behaviour of wet deposited embankment on an existing dry deposited one.

Why is it important?

The evolution of stored waste passes by three stages during which its parameters vary. Therefore it is with interest to take in account the variation of deposited phosphogypsum properties to properly predict its behaviour.
