1. (40 pts) A conventional cantilever retaining wall is constructed as shown in the figure below.The soil behind the wall is homogenous and has the properties shown. a) (5 pts) What is the appropriate lateral earth pressure to be used (at-rest, active, or passive)? Why? ) (15 pts) Draw the lateral pressure diagrams for the wall configuration and loading.Use the Rankine method for calculating the lateral earth pressure coefficient. c) (10 pts) What is the total resultant lateral force (including the surcharge, earthpressure and water pressure)? d) (10 pts) What is the location of this resultant lateral force relative to the base of the wall?
