Thanks to all the contributors.
To clarify, yes I am looking for the "lab" or intact rock c and phi values inferred via empirical relationships from the UCS and associated Secamt and Tangent E-value and poisson's ratios.
I do not currently have the ability to conduct the triaxial lab testing...
Good Day All,
I have some test results on Mudstone materials (Generally 3-10MPa UCS) where the Secant and Tangent E-value aswell as the Secant and Tangent Poissons Ratios were determined with the specific failure load and associated UCS of the rock core specimen.
I am looking for some...
We need to design and construct large diameter piles to take relatively high loads.
The friction Piles are constructed using a reverse circulation drill rig, to drill into a Shale type rock.
In an attempt to understand the properties of the weaker rock materials, various 110mm vertical...
Thank you for the contributions, although it did not do any good in solving the problem, however, and I do not want to start a run-away-fire here, Patgeotech is quite correct in making reference to other parts of the world and the classification and identification system used there.
For...
Hi All,
I have found a paper by R.K Rowe called "A design method for drilled piers in soft rock" from a Canadian Geotechnical Journal. This paper addressed methods on how to design with low RQD rock and tight settlement criteria (duplicating the conditions that I have), but is based on case...
