Problem 4. (20 points) Figure 11.11 illustrates the notation and sign conventions for the Mononobe-Okabe extension of the Coulomb analysis of dynamic loading on a retaining wall. Consider a vertical retaining wall 7 m high with horizontal backfill. Assume that, for the soil, Mass density p = 1.9 Mg/m3 Cohesion c = 0 Friction angle o = 36 Friction angle between soil and wall 8 = 18° Assume the horizontal seismic loading coefficient kn = 0.20 and the vertical coefficient is 0. Calculate the active load P that the soil exerts on the wall due to the combination of static and seismic effects.
