Large-scale Direct Shear

Direct shear tests is an important in the case of Geotechnical Engineering (Soil Mechanics and Foundation) to determine soil strength parameters in terms of consolidated-drained (CD). In this test, first soil under the specific vertical stress become consolidated, then while stabilizing vertical stress, shear stress is set to speed, apply to soil sample until the sample is ruptured. The maximum shear stress for a specific vertical stress, gives the coordinates of a point. Tests are usually performed with three different vertical stress and thus coordinate system "shear stress - vertical stress" three points is obtained that draw the best line passing through the points, soil strength parameters of (C, Φ) are determined.

Direct shear test apparatus, which is manufactured by Soil Mechanic Industries of Iran Co., designed and produced accordance with international standards such as ASTM.

Standards: ASTM D3080, BS EN 1377,
