2.3 Bearing capacity of footings on slopes The N,factor probably should be adjusted to N to account for the reduction in passive pressure on the slope side of the wedge when the base is either within the b/B<2 zone on the top of the slope or when b/B=0. ■ Saran et al.(1989)proposed an analytical solution to account for this reduction. A simple solution that compares reasonably well with test results (on models)is as follows: ①Assume no reduction of N,for b/B≥2； Use the Hansen N,factor and adjust as follows:a. d. 图 2.3 Bearing capacity of footings on slopes ▪ The Nγfactor probably should be adjusted to Nγ ’to account for the reduction in passive pressure on the slope side of the wedge when the base is either within the b/B<2 zone on the top of the slope or when b/B=0. ▪ Saran et al.
