Check the stability of the reinforced cantilever retaining wall against overturning only.

Given:

Unit weight of concrete = 24kN/m3

Unit weight of soil = 18kN/m3

Angle of friction φ = 30?

Expert Solution

From the given values it cannot be done. Additional information is needed regarding in the form of classification of soil depths. The procedure to solve it is given below. please follow it u will get the answer.

The factor of safety against overturning is calculated as

1. The overturning moment is calculated as

Where g is unit weight of soil, K_a is active pressure coefficient, and H is the height from top of earth to bottom of footing, q is surcharge.

2. The resisting moment is calculated as

where Ws,Wf,We,Wk,Wq are weight of stem, footing, earth, key and surcharge, X_s,X_f,X_e,X_k,X_q are distance from the center of stem, footing, earth, key, and surcharge to the rotation point at toe.

3. The factor of safety against over turning is calculated as

If the F.O.S greather than 1.5. It is said to be stable. Stability against overturning is checked in this manner.

A retaining wall against a mud slide is to be constructed by placing 1.2 m-high rectangular concrete blocks (ρconcrete = 2700 kg/m3 ) side by side, as shown in Figure 1. The friction coefficient between the ground and the concrete blocks is f = 0.3, and the density of the mud is about 1800 kg/m3 . There is concern that the concrete blocks may slide or tip over the lower left edge as the mud level rises. a) Determine the...

A ladder of unit length leans against a wall (y-axis) as its bottom slides along the ground (x-axis). As the ladder slides from vertical to horizontal, one end remains in contact with the wall while the other end remains in contact with the ground. Find : (1) Derive an algebraic equation describing the trajectory traced out by the midpoint of the ladder. What is the shape of the trajectory? (2) Derive an algebraic equation for the envelope bounded by the...
