Q#4:                                                                                                                                                        Plate load test performed on a uniform deposit of sand and the following observations were recorded. The size of the plate was 45cm x 45cm. Plot the Pressure-Settlement Curve and determine the safe load on a footing 2m x 2m if the settlement is not to exceed 40mm.   Pressure (kPa) 2 4 8 12 16 24 Settlement (mm) 3 6 20 40 60 100   Note: Write the proper answer in word format Subject: Geotechnical Design

For the conditions described, calculate the soil rigidity index Ir:(a) Soil modulus of elasticity is 150 ksf, Poisson’s ratio is 0.40, soil unit weight is 115 pcf, cohesion is 600 psf, and angle of internal friction is 28°. Find Ir for a point 10 ft below the soil surface.(b) Modulus of elasticity is 18 ksf, Poisson’s ratio is 0.45, soil cohesion is 1,200 psf (undrained shear), and soil unit weight is 105 pcf. Find Ir for a point 8 ft below the soil surface.(c) Modulus of elasticity is 200 ksf, Poisson’s ratio is 0.30, angle of internal friction is 35°, and soil unit weight is 122 pcf. Find Ir for a point 10 ft below the soil surface.
