Model numeryczny układu pal jet-grouting - grunt

In the paper an elastoplastic FEM models for jet-grouting pile soil system are proposed. An real interlace zone around the jet-grouting core is introduced. All zones are modelled using the Coulomb-Mohr's constitutive laws. The most important task undertaken in the paper is parametric evaluating for soil, interface zone and jet-grouting core. The parameters for the soil and the jetgrouting core should be known from the laboratory tests (unconfined compressive test, triaxial tests) but for obtaining the parameters for the interface the author used the results of loading test and back analysis.
