Question:

Refer to the retaining wall in Problem 15.1. Estimate the passive force, Pp, per unit length of the wall using Zhu and Qian’s (2000) method of triangular slices. Use Eq. (15.18).

Data From Problem 15.1

A retaining wall has a vertical back face with a horizontal granular backfill. Given: H =  6 m, γ = 18.5 kN/m3, ϕ' = 40ο, and δ' = 1/2 ϕ'. Estimate the passive force, Pp, per unit length of the wall using Terzaghi and Peck’s (1967) wedge theory (Figure 15.4).
