A series of three Direct Shear Tests have been conducted on a certain soil type. The tests were performed on a circular 10 cm-diameter soil sample. The results of these tests taken at the peak failure stress are as follows: Normal Load Shear Load Normal Stress | Shear Stress Test Number (kN) (kN) (kPa) (kPa) 1.178 0.785 1.963 1.374 2.356 256 1.571 a) Use the space provided below to plot the failure envelope and obtain the shear strength parameters.

Geotechnical Engineering 4. A dry sand sample is subjected to direct shear testing at its normal (in situ) water content. Tw performed on this sand. For one of the tests, the sample shears at a stress of 100 kPa when the norma is 150 kPa. In the second test, the sample shears at a stress of 200 kPa when the normal stress is 300 Determine the cohesion and the angle of internal friction of this sand sample b
A drained direct shear box test was performed on a sample of saturated sand. The normal effective stress of 467 kPa was constant throughout the test, and the initial sample dimenstions were 60 mm x 60 mm in plan x 30 mm deep. In the vicinity of peak shear stress, the data recorded were: (20 points) Shear Stress, τ (kPa) 42.5 43.1 42.8 Relative horizontal displacement x (mm) 0.30 0.40 0.80 Upward movement of the shear box cap y (mm)...
