Designing singular jet grouting column for sandy soils
(Springer Verlag, 2018) Karahan G.N.; Sivrikaya O.
In this study, the bearing capacity and settlement values of jet grouting columns with the same diameter in very loose and loose sandy soils were estimated by theoretical approaches and numerical analysis depending on the change in the length of the jet grout columns and soil relative densities, and those values were compared with each other. The changes in bearing capacity and settlement values obtained from soil parameters, jet grouting column length and method differences were examined. In the designing of the jet grouting column, these factors should be determined carefully and correctly. The bearing capacity of the jet grouting column is calculated by the theoretical approach considering as a pile. The settlement values of the jet grouting column were calculated by semi-empirical, empirical and theoretical methods. In numerical analyses, single jet grouting column was modelled with Mohr Coulomb and Hardening Soil models in axial symmetry model and the bearing capacity and settlement values of singular jet grouting column were determined. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.
