Sensitivity of clays

Sensitivity of clays

Sensitivity of clays

(OP)
Hello,
i am just wondering , do you guys calculate the Sr sensitivity in any given project or only for important ones ?

RE: Sensitivity of clays

What's the difference between a regular project and an important one?

RE: Sensitivity of clays

If I do a vane test I certainly do the remoulded Su for a measure of the sensitivity. The question, though, is if you don't do the vane test, how to you measure the sensitivity? And, in line with Ron, if I can measure the sensitivity as part of teh investigation, it would go on all reports.

RE: Sensitivity of clays

similar to BigH, the only time i ever calculate a sensitivity ratio is following measuring an Su in a shear vane test (e.g. 100 kPa) and then a remoulded shear vane (30kPa) and then dividing one by the other. so in this example, Sr=0.3 or 30%. I guess you could get a sensitivity during a triaxial test too

Thanks all of you

RE: Sensitivity of clays

my apologies - in my example i should have said Sr=100kPa/30kPa = 3.33
