A footing with an embedment of 2 m is embedded in a sand with a unit weight of 125 lb/ft3anda f′ of 36°. If the footing is subjected to a horizontal load that causes it to move horizontally,compute the total active and passive resultant forces acting on the footing.

Question attached

A square footing 5 ft by 5 ft supported on a sandy stratum is designed to carry a column loading of 250,000 lb. The unit weight of the sands underlying the footing location vary between 120 and 125 pcf. Estimate the foundation settlement to be expected using the subgrade reaction method. (Neglect the weight of the footing.)

A square footing 3 m x 3 m is supporting an axial load of 650 kN. The weight of the soil is aasumed to be 17.32 kN/m^3. Compute the vertical stress increment due to this load at a depth of 1.5 m below the center of the footing using the approximate method. a. 51.46 kPa b. 32.10 kPa c. 76.54 kPa d. 50.56 kPa
