Chapter 15, Problem 15.19P

Refer to Figure 15.27a. For the braced cut, H = 6 m, Hs = 2 m, γs = 16.2 kN/m3, angle of friction of sand, ϕ s = 34 ° , Hc = 4 m, γc = 17.5 kN/m3, and the unconfined compression strength of the clay layer, qu = 68 kN/m2.

a. Estimate the average cohesion, cav, and the average unit weight, γav, for development of the earth pressure envelope.

b. Plot the earth pressure envelope.

(Derive the Rankine active earth pressure of a soil at a depth of z using Mohr Circles, and failure envelope when the retaining wall has horizontal ground surface and the unit weight, cohesion, and internal friction angle of the soils are 7, c, and ø. In addition, what is the maximum depth of tensile crack at the retaining clay when Y =15.72kN/m³, cu=6.77kN/m² 9 and ø=30°) Ir 10000
A cut was made in a homogeneous clay soil to a depth of 8 m as shown in below Figure. The total unit weight of the soil is 18 kN/m³, and its cohesive strength is 25 kN/m². Assuming a = 0 condition, determine the factor of safety with respect to a slip circle passing through the toe using Swedish circle method. Consider a tension crack at the end of the slip circle on the top of the cut. 8 m R = 12 m 39⁰ 6m Trial slip circle y = 18 kN/m³ c'= 25 kN/m² o'=0
1. Side slopes for rock fill 1V:2H. Calculate the minimum crest width of a breakwater using B = 3*kΔ*(W/γa)1/3 . Given data: Stone weight = (8) t, Specific weight = 2,7 t/m3, Layer thickness coefficient =1,00 and Porosity percentage = 37 2.  For cubed shaped stone (or concrete), determine dimension of the stone for weight: W = (10+a) t, specific weight: γa = 2,4 t/m3
