The cross section of a braced cut supporting a sheet pile installation in a clay soil is shown in Figure 14.21. Given: H = 8 m, γclay = 19 kN/m3, ϕ = 0, c = 42 kN/m2, and the center-to-center spacing of struts in plan view, s = 3.5 m. a. Using Peck's empirical pressure diagrams, draw the earth pressure envelope. b. Determine the strut loads at levels A, B, and C.
