Abstract

This study presents a numerical investigation on development of vertical axial force–shear force (V–H) capacity envelopes of strip footing placed on the surface of cohesionless soil having different ϕ overlying on the soft rock with constant GSI, mi, and D values. Force-based swipe analyses are conducted using OptumG2 following lower bound solution for finite-element limit analysis. The results are presented in terms of variation in bearing capacity ratio (Bcr) with soil-rock thickness ratios (Ts/B) and V–H capacity envelope varying with ϕ and Ts/B. It is found that the normalized capacity envelope for strip footing placed at top of pure cohesionless soil is almost similar for any value of ϕ. Further, for a particular Ts/B, the shape of normalized V–H capacity envelope increases with the increase in higher ϕ values. The normalized capacity envelope was found unaffected by Ts/B value beyond 4.0, for a soil with any value of ϕ.
