Figure P14.1 shows a cantilever sheet-pile wall penetrating a granular soil. Here, L = 4 m, L2 = 8 m, y = 16.1 kN/m², yu = 18.2 kN/m², and &' = 32°. a. What is the theoretical depth of embedment, D? b. For a 30% increase in D, what should be the total length of the sheet piles? c. Determine the theoretical maximum moment of the sheet pile.

Which of the two walls in Figure below gives the larger horizontal force? (Show calculations.)

Quantity Surveying.   Plz, answer all the question parts.

3. Compute the resultant lateral force for the soil-wall system shown in Figure 3. You may ignore tensile cracks. Use • A- Coloumb • B - Rankine 0=30°, y=20kN/m³ 4m Ground water table 7m c=50KN/m², p=10°, y=18KN/m³ 0=25°, y=20KN/m³ 8 m Gravity wall Figure 3
