a$)$ Design the retaining wall with respect to stability in terms of overturning moment,

sliding, and slipping. Also check the wall thickness against shear, bearing pressure

under the footing, and check the required length of the retaining wall base. provide the

reinforcement design.

b$)$ Provide detailed drawings of reinforcement of the retaining wall based on your

structural design.

c$)$ Discuss and conclude your design work.
