Geotechnical Engineering
9. A damp sand sample is subjected to direct shear testing at its normal (in situ) water content. Two tests are performed. For one of the tests, the sample shears at a stress of 100 kPa when the normal stress is 135 kPa. In the second test, the sample shears at a stress of 145 kPa when the normal stress is 225 kPa. Plot the test data and determine the value of the "apparent cohesion" and the corresponding...

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)...
