Internal Friction Angle

Internal Friction Angle

Internal Friction Angle

(OP)
Im looking for an internal friction angle for weathered bedrock for the design of a soldier pile and lagging wall. The description from the soil report is as follows

Medium to soft, moderate to moderately severely weathered, dark gray, amorphous, ARGILLITE, with very close (<2"), moderately dipping (35deg-55deg) joints/fractures. RQD from 0 to 10%.

Any recommendations?

RE: Internal Friction Angle

Really, you need to ask the author of the soil report.  Even if you have to pay for a few more hours of effort, it's their experience in the local market that's important.

agreed

RE: Internal Friction Angle

p.s., ask them what "amorphous argillite" means.  It doesn't mean anything to me as argillite would be like a claystone (i.e., clay minerology) and amorphous means lack of mineralogy.
