Q: Results of a sieve analysis for Soils A, B, and

Results of a sieve analysis for Soils A, B, and C are given below. To obtain a more representative sample for further geotechnical testing, a ternary blend was created by uniformly mixing 8000 kg of e...

Q: Determine the factor of safety against heave on the downstream side of

Determine the factor of safety against heave on the downstream side of the single-row sheet pile structure shown in Figure 9.30. Use the following soil and design parameters: H1 = 7 m, H2 = 3 m, thick...

Q: Figure 9.31 shows a concrete dam. Consider Case 1

Figure 9.31 shows a concrete dam. Consider Case 1 without the sheet pile and Case 2 with the sheet pile along the upstream side. Draw flow nets for both cases. Determine the value of q/k for both case...

Q: A sand has Gs = 2.68. Calculate the hydraulic

A sand has Gs = 2.68. Calculate the hydraulic gradient that will cause boiling for e = 0.4, 0.5, 0.6, and 0.7. Plot a graph for icr versus e.

Q: An exploratory drill hole was made in a stiff saturated clay (

An exploratory drill hole was made in a stiff saturated clay (see Figure 9.28). The sand underlying the clay was observed to be under artesian pressure. Water in the drill hole rose to a height of 18...

Q: Refer to Problem 9.6. It is required to make

Refer to Problem 9.6. It is required to make an open excavation of 18 ft in the saturated clay. To avoid heaving, the cut will be filled with water similar to that shown in Figure 9.6. What should be...
