engineering recuitment GATE CE 2023-24 Test Series Soil Mechanics and Foundation Engineering Shear Strength
A conventional CD test was conducted on a saturated clean sand sample by using the following steps.
1. Set cell pressure to 250 kPa and allow the sample to consolidate with its drainage valve open at 100 kPa back pressure.
2. shear the sample without any change in the drainage condition.
the sample failed when the deviator stress reached 300 kPa.
Determine the ratio of the shear stress and normal stress on the failure plane. (round up to two decimal places)
Enter numerical value using the virtual keypad. Round off where necessary.
