17.6 ung Coulomb's earth pressures. It is required to design a cantilever retaining wall to retain a 5.0 m high sandy backfill. The consultant suggests the dimensions and soil properties shown in Figure P17.6 and requires that the wall be checked for stability with respect to sliding and overturning based on the active earth pressures determined using 0.5 mm 110° EDT Sand y = 18.5 kN/m3 6' = 36°...
Figure 15.45 shows a gravity retaining wall retaining a granular (c' = 0) backfill. The same soil is present at the bottom of the wall and on the left. The unit weight and the friction angle of the backfill are 18.5 kN/m3 and 35°, respectively. The unit weight of concrete is 24.0 kN/m3. Determine the factors of safety with respect to overturning, sliding, and bearing capacity failure. Use Rankine earth pressure theory.

A 4m high, vertical retaining wall supports Silty SAND backfill with a horizontal surface. There is a hydrostatic horizontal water table at 1 m below the ground surface. The soil has bulk unit weight = 20 kN/m3, effective cohesion=5 kPa, and friction angle= 30o. What is the value of the water force on the wall? At what distance above the base of the wall does it act?
please answer 2 and 3
i would really appreciate it :)

The 4 m tall concrete retaining shown in Figure 2 has the following properties: Backfill (Coarse sand): Ym = moist unit weight = 19.2 kN/m d' = effective friction angle = 40° The groundwater table will remain far below the wall, and the wall friction angle is 20°. Assume the backfill is not sloped and the wall has no batter. The wall moves sufficiently to develop the active...
