20.04.2021 Try taking lateral bearing capacity equal to 0.33 to 0.67vertical bearing capacity, with a further reduction near the surface where the rock isnt confined. 0.33 for when RQD is zero and 0.67 for when RQD is high. See links below for some options on near-surface reduction. This is of course a rough method meant for order-of-magnitude checking.

Abstract: Basal bearing capacity calculation is one of the important issues for soil nailing wall design. In Chinese excavation engineering, the bearing capacity of soil nailing walls is usually taken into consideration with the basal stability analysis. Soil nailing wall models are established in the Plaxis3D. Finite element method is employed to study the foundation soil′s failure mode ...
