Abstract
Triaxial tests of soils, rocks and earth materials present an important part of laboratory geomechanical investigations. They give us many parameters, which can later be used in geotechnical analyses. As a rule conventional triaxial test are performed in cylindrical triaxial apparatus. A specimen, which is built in apparatus, is incrementally loaded by different stresses. Time development of stress and deformation changes follow during different stress states. The described procedure is retardatory and results can even be unreal when individual stress increments are high, followed by high gradients of pore pressure. An extent of triaxial tests performed in practice is often unpretentious, mostly due to high price and long duration of test execution. Therefore it is reasonable to supplement conventional incremental tests. It was introduced two typical test procedures; static continuously loaded triaxial tests and cyclic (dynamic and repetitive) triaxial tests. Presented research project treats the execution of cyclic triaxial tests of soil. The research project will be performed in the Laboratory of soil mechanics, Faculty of Civil Engineering, University of Maribor. The essential equipment comprises cylindrical triaxial apparatus with a cell, a press with appurtenant electro-mechanic equipment, measuring equipment and computer hardware and software equipment. Ministry of Science RS supported the purchase of equipment in 2001. Review of cyclic triaxial test on different materials (Drava river saturated sands, carboniferous slates from the Trojane hilly area, gravely sandy siltstone from the Stože landslide and pavement granular base material) shows wide applicability of cyclic triaxial tests.
