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
Two parallel road tunnels are being constructed for 6 lanes in the basalts. The tun- nels are D-shaped with diameter (B) of around 16 m and 2 m high side walls with clear spacing of 20 m. The maximum overburden (H) is 165 m. The rock mass parameters are, RMR = 73, Q = 10, Ja=1.0, Jr = 3.0 and Jw = 1.0 (minor seepage from side walls). The construction engineers want rapid rate of tunnelling and life of support system should be 100 years. The uniaxial compressive strength of SFRS is 30 MPa and its flexural strength is 3.7 MPa.
