Hi,
I'm designing an anchor block for a cable stay of a transmission pole. When calculating shearing resistance on the perimeter of the anchor block (S2), the concrete-to-soil friction angle needs to be found. The internal friction angle of the soil is 36 degrees. Any tips for calculating concrete-to-soil friction angle would appreciated.
Thanks

In this case ( granular soil) , you may consider the friction factor ( µ = TAN Φ ) and for 35 degr. µ = 0.7.
I will suggest you to use friction factor 0.4 for WSD loading and look for factor of safety against sliding =1.5

This approach is OK for dry conditions .If there is a risk that submerged conditions may develop , you are required to use effective wts for soil and anchor block. Another issue , wp membrane and tanking the surfaces of the block with bitumen epoxy.


According to the grace of God which is given
unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. . . .
