ASTM D3080 04 Standard Test Method for Direct Shear Test

1. Scope. 1.1 This test method covers the determination of the consolidated drained shear strength of a soil material in direct shear. The test is performed by deforming a specimen at a controlled strain rate on or near a single shear plane determined by the configuration of the apparatus.

DIRECT SHEAR TEST Swedish College Of Engineering

DIRECT SHEAR TEST OBJEVTIVES To determine the shear strength parameters for a given soil using the direct shear test. INTRODUCTION The test is carried out on either undisturbed samples or remoulded samples. To facilitate the remoulding purpose, a soil sample may be compacted at optimum moisture content in a compaction mould.

Triaxial Shear Test on Soil Procedure,Advantages

Triaxial shear strength test on soil measures the mechanical properties of the soil. In this test, soil sample is subjected to stress, such that the stress resulted in one direction will be different in perpendicular direction. The material properties of the soil like shear resistance, cohesion and the dilatancy stress is determined from this test.
