D2850-Standard Test Method for Unconsolidated-Undrained Triaxial Compression Test
on Cohesive Soils (2007).
Therefore, according to the measured data in the triaxial compression test
and the formula (21), the elastic modulus of each modified soil in Table 1 can be concluded.
Aimed to study the water-softening for mechanical properties of the Zigong argillaceous siltstones under different degree of weathering, this paper selected three types of mechanical tests: uniaxial compression test, triaxial compression test
, and direct shear test.
Triaxial compression test
is generally used to determine the intact rock properties required for underground mining designs.
ASTM D4767--04 Standard Test Method for Consolidated Undrained Triaxial Compression Test
for Cohesive Soils, 2004.

for Cohesive Soils.
Development of new triaxial compression test
apparatus for geomaterials on industrial X-ray CT scanner.
The result of cyclic shear stress of torsional single shear test is lower than that of triaxial compression test
, while the mean principal stress is dependent of initial shear stress.
The confining pressure of triaxial compression test
were set at 1, 4, 9 and 14 MPa for sandstone, 1 and 9 MPa for siltstone, 1, 4 and 9 MPa for coal specimens in addition to the uniaxial compression tests.
The relationship between dry unit weight and internal friction angle was identical for different strain rates, regardless of water content, as shown by the triaxial compression test
results plotted in Figure 4.
