Impact of Plant Root Morphology on Rooted‐Soil Shear Resistance Using Triaxial Testing [PDF]
, 2020 Mechanical reinforcement by plant roots increases the soil shearing strength. The geometric and distribution characteristics of plant roots affect the soil shearing strength. Current research on the shear strength of rooted-soil is mostly based on direct

Liquefaction of Saturated Sand in Triaxial Torsion Shear Test
Soils and Foundations, 1972 ABSTRACT Strain-controlled cyclic torsion tests were run on a saturated sand using a triaxial torsion apparatus in which the vertical piston was designed so that its cross sectional area was equal to that of the specimen. In the first series of tests, a cyclic twist was applied while keeping the principal stress ratio constant.

Effect of the optimum and residual moisture content on the strength characteristics of unsaturated sands [PDF]
E3S Web of Conferences, 2023 Soil exists mainly in unsaturated conditions. Therefore, accurate prediction of the soil shear strength for unsaturated conditions also becomes equally important for the geotechnical design of earth structures.
