2. Direct shear test - Wikipedia

   en.wikipedia.org/wiki/Direct_shear_test

   A direct shear test is a laboratory or field test used by geotechnical engineers to measure the shear strength properties of soil [1] [2] or rock [2] material, or of discontinuities in soil or rock masses. [2] [3] The U.S. and U.K. standards defining how the test should be performed are ASTM D 3080, AASHTO T236 and BS 1377-7:1990

3. Geotechnical investigation - Wikipedia

   en.wikipedia.org/wiki/Geotechnical_investigation

   Direct shear test ASTM D3080. The direct shear test determines the consolidated, drained strength properties of a sample. A constant strain rate is applied to a single shear plane under a normal load, and the load response is measured. If this test is performed with different normal loads, the common shear strength parameters can be determined ...

4. Tilt test (geotechnical engineering) - Wikipedia

   en.wikipedia.org/wiki/Tilt_test_(Geotechnical...

   Tilt test on a fitting discontinuity. In geomechanics, a tilt test is a simple test to estimate the shear strength parameters of a discontinuity. [1] [2] Two pieces of rock containing a discontinuity are held in hand or mounted in test equipment with the discontinuity horizontal. The sample is slowly tilted until the top block moves.

5. Dilatancy (granular material) - Wikipedia

   en.wikipedia.org/wiki/Dilatancy_(granular_material)

   On the other hand, when a granular material starts in a very loose state it may continuously compact instead of dilating under shear. A sample of a material is called dilative if its volume increases with increasing shear and contractive if the volume decreases with increasing shear. [7] [8] Dilatancy is a common feature of soils and sands. Its ...

8. Shear vane test - Wikipedia

   en.wikipedia.org/wiki/Shear_vane_test

   The shear vane test is a method of measuring the undrained shear strength of a cohesive soil. The test is carried out with equipment consisting of a rod with vanes mounted to it that is inserted into the ground and rotated. A gauge on the top of the rod measures the torque required to cause failure of the soil and provides a conversion to shear ...

9. Soil compaction - Wikipedia

   en.wikipedia.org/wiki/Soil_compaction

   Soil compactors are used to perform test methods which cover laboratory compaction methods used to determine the relationship between molding water content and dry unit weight of soils. Soil placed as engineering fill is compacted to a dense state to obtain satisfactory engineering properties such as, shear strength, compressibility, or ...
