Experimental study on effects of various factors on mechanical behavior of clay

Abstract

In this study, we conducted triaxial compression elongation test, hollow cylindrical torsional shear test and simple shear test on undisturbed viscous soil and reconstituted clay, so that loading direction, loading mode, loading speed and compaction stress history on the static mechanical properties of viscous soil. Brittle strain softening, which is cited as a representative dynamic behavior of the non-disturbing clay with outstanding skeleton structure, is observed depending on the loading speed by triaxial compression test, and it is a small loading speed and a simple shear mode, It was shown that the degree of softening decreased and it became impossible to observe it, so it was not an absolute mechanical property of the clay. In addition, it was shown that the anisotropy attributable to the initial structure is small in the non -disturbing viscous soil sample used in this study.
