DP SPT for weak rock

DP SPT for weak rock

DP SPT for weak rock

(OP)
Anybody can tell me about correlation for weak or fractured rock investigated by DP or SPT
I've found only pressuremeter menard, Plim=spt/20, from Doix & Bustamente for non fractured marl and similar.
Thanks

RE: DP SPT for weak rock

Italicus - I wouldn't even try.  Perhaps for "special" type rock (e.g., chalk) there might be some correlations but even for weak fractured shale - the blow counts at 50/1" penetration - what is it going to tell you?  You have something more than "soil"???

RE: DP SPT for weak rock

Agreed.  I think it's a waste of time.

What are you trying to accomplish?



Please see FAQ731-376 for great suggestions on how to make the best use of Eng-Tips Fora.  See FAQ158-922 for recommendations regarding the question, "How Do You Evaluate Fill Settlement Beneath Structures?"

I am looking for correlation between pressuremeter parmater (modulus / limit pressure) and SPT or UCS
