Triaxial Test 1

[AdityaDeshmukh]

Hi,
If I get a sample from 2m below GL and the ground has unit weight of 20 KN/m^3. How to calculate stresses for tri axial loading test to simulate ground conditions ?
Confining or cell pressure and deviator stress.

Thanks in advance.

Above or below the water table? Where is water table?

 

[AdityaDeshmukh]

for both cases.

Apparently you have no background in geotechnical parameters. Your query requires more parameters than you have given for a reasonable answer. Perhaps you should consult a local geotechnical engineer for guidance with local conditions. Each increment of the depth to water table will give a different answer.

The test pressures will be dependent on much more information than you have provided here or you would be permitted to provide here under most contractual conditions. As Ron suggests, you should contact a geotechnical engineer who will be able to apply their knowledge of the ground conditions, geotechnics, regional geology, etc. and determine representative test pressures.

use back pressure 10kPa & cell pressure: 30kPa, 50kPa & 90kPa
