. You are supporting an excavation with a shoring system to support a cut of 25’ deep in silty clay soil. What isthe maximum pressure on the shoring at the subgrade/dredge line if the soil properties include ϒ = 117 pcf, c = 220 psf, and φ = 22o . What is the angle of the failure plane from the face of the trench

The following case study involving a failure in fissured over-consolidated clay slope was reported by Henkel and Skempton in 1954. The failure occurred in 1952 in Jackfield, Shropshire, England. The slope profile is shown in Figure 1. The failure was a translational slide where the average depth to the failure plane was 17 ft. The ground water table was very near or at the surface. The peak strength parameters of the over-consolidated clay are: cohesion, c'= 220 psf and friction...
