Abstract: With application of FlAC3D,the natural large-scale block model is built to make the true triaxial tests for the tailings geotextiles compound to reflect the macro physical and mechanical properties and to mainly consider the performance of the principal stress on the numerical tests.Through the tests results,the change rule curve for the whole process of the axial stress and displacement and its mechanical properties are analyzed.The tests result provides a certain significance for the research of dry storage of the tailing geotextiles compound and the design,research and implementary of the tailings embankment.
