CONSOLIDATION TESTING USING TRIAXIAL APPARATUS. FINAL REPORT

During this research study, a sophisticated automated triaxial apparatus was procured to study the feasibility of using one sample to obtain shear strength and consolidation characteristics of a particular soil. After completion of the test program, it was concluded that the triaxial system was effective in obtaining multiple engineering properties of soils from one sample. These properties included strength, stress versus strain behavior, consolidation characteristics and permeability of a soil. It was also concluded that the triaxial consolidation characteristics are not to be used to predict the in-situ three dimensional consolidation behavior of soils. This is due to the fact that the three dimensional consolidation is very much affected by the stress path and the boundary conditions; but the conventional triaxial consolidation cannot simulate all in-situ loading and boundary conditions. The sophisticated testing system developed during this study is capable of carefully evaluating triaxial consolidation characteristics and shear strength of various soils. Therefore, it is recommended that this equipment be used in all projects requiring shear strength, stress versus strain properties, and consolidation characteristics of soils.
