UNDRAINED CYCLIC STRENGTH OF COMPACTED ROCKFILL MATERIAL FROM TRIAXIAL AND TORSIONAL SIMPLE SHEAR TESTS

Evaluation of undrained response from drained triaxial shear tests: DEM simulations and Experiments

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

evaluation of mechanical behaviour of sandstone and andesibasalt rockfill materials using triaxial & direct shear tests

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

Effects of Ballast Degradation on Shear Strength Behavior from Large-scale Triaxial Tests

Ballast, typically comprising large sized aggregate particles with uniform gradation, is an essential layer in the railroad track substructure. Functions of ballast include facilitating load distribution and drainage, maintaining track geometry and track stability, and providing track resilience and noise absorption. Throughout its service life, ballast goes through changes in gradation and par...

Studies on Dynamic Character of Saturated Soft Clays through Cyclic Torsion Shear Tests

A large number of cyclic torsional shear tests on saturated soft clay under unconsolidated undrained condition have been carried out. The changing law between accumulative generalized shear strains vs. failure numbers has been analyzed and a cyclic shear strength curve has been received based on cyclic torsional shear tests. According to the test results, the criterion of saturated soft clay is...
