Unformatted text preview: Review #4 Part B 5. Consider a 6m high retaining wall that has a vertical back face with a horizontal backfill. A vertical point load of 8.92 kN is placed on the ground surface at a distance of 3 m from the wall. Calculate the increase in the lateral force on the wall due the point load. 6. Consider a 6m high retaining wall that has a vertical back face with a horizontal backfill. A line load of 8.92 kN/m is placed on the ground surface at a distance of 3 m from the wall. Calculate the increase in the lateral force on the wall due the point load. 7. Consider a 6m high retaining wall that has a vertical back face with a horizontal backfill. A 2m wide strip load of 8.92 kPa is placed on the ground surface at a distance of 3 m from the wall. Calculate the increase in the lateral force on the wall due the point load. 8. Using Coulomb’s method, compute the active pressure acting on the reinforced concrete retaining wall shown below. 9. The cross section of a retaining wall is shown below. Calculate the factors of safety with respect to sliding, overturning and bearing capacity. The ultimate BC of the soil is 10.21 kip/ft2. Pa = 8.18 kip/ft and Pp = 3.31 kip/ft. assume ca = 2/3c. ...
