Internal Friction Angle

[jguyder]

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?

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

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.
