"Bay Clay Loam" type of soil
"Bay Clay Loam" type of soil
(OP)
Hi everyone,
I am working on a 4-storey residential/commercial building resting on a "Bay Clay Loam" type of soil (Located near the Bay from the word itself). As I am still awaiting for the tests(Shear wave velocity, SPT and undrained shear strength) to be done, I would like to ask your opinion if the soil is categorized as stiff soil or soft soil? In my observation, it has a fine granules which is friable when dry, but very sticky when wet.
Thanks for the help.

N = 0-2: very soft
N = 2-4; soft
N = 4-8: firm or medium (USA)
N = 8-15: stiff
N = 15-30: very stiff
N > 30 hard
How did you collect the sample without the SPT??

I am still waiting for the test results on this. Appreciate your input.

You need to spend money on proper drilling and undisturbed tube samples. You need to baby your tubes and let them ride vertically in the comfort of your car (i.e., not the back of some pickup truck or otherwise in the care of the drillers).
Unconsolidated undrained triaxial strength testing seems indicated (doctor talk, eh?).
This being the San Francisco Bay Mud, eh?
