Calculation of Factors of Safety Against Overturning and Sliding for a Cantilever Retaining Wall
[ Ссылка ]
The engineering problem statement states,
For the reinforced concrete cantilever retaining wall shown below, calculate the factor of safety against overturning and sliding given the following parameters:
Cohesionless soil, c = 0
Weight of Backfill: 110 lbs/ft^3
Angle of Internal Friction: 30 degrees
Coefficient of Friction Between Concrete and Soil: 0.5
Weight of Reinforced Concrete: 150 lb/ft^3
calculate the coefficient of active earth pressure, ka, using the Rankine theory
compute the lateral force resultant, Ra, due to the active earth pressure
find the overturning moment, Mo, caused by the lateral force resultant due to the active earth pressure
determine the balancing moment that is responsible for resisting the overturning moment on the cantilever retaining wall
calculate the factor of safety against overturning
find the factor of safety against sliding
