ABSTRACT
The back analysis method was used for estimation of relevant municipal solid waste (MSW) parameters which are difficult to obtain in a direct way. The reference data were collected during field investigations comprising three stage loading test of a 3 m high vertical cut excavated at the edge of a MSW slope. It has been demonstrated that the 2-D behavior of MSW can be simulated with a sufficient accuracy using basic Mohr-Coulomb constitutive model requiring five input parameters, provided tensile stresses are accounted for. Presented are comparisons of experimental and computed displacements, as well as the estimated set of MSW mechanical parameters. An accompanied stability analyses confirmed high stability potential of MSW cuts.
