Micaceous soils
(OP)
Is there any information on micaceous soils? (e.g. bearing capacity, phi angle, allowable side friction, or lateral soil modulas) Can you use "blow count engineering": my driller did not produce any samples suitable for testing? The stuff feels so greasy I wonder whether there is any side friction for drilled piers.





RE: Micaceous soils
SPT would be suitable. Indeed, difficult to obtain good undisturbed sample. Re shaft resistance, if you are not comfortable try belled piers and design based on end bearing.
RE: Micaceous soils
I would like to use end bearing and/or a bell. Problem is this is an existing pier group and I have uplift to consider. Can I use blow counts to estimate a phi angle and then a friction coef.
