a) A square foundation is 2 x 2 m in plan is to be constructed. The foundation has friction angle of o= 34° and c = 20 kN/m?. The unit weight of the soil, y, is 20 kN/m³. Determine the allowable gross load on the foundation with a factor of safety of 3. Assuming that the depth of foundation (Df) is 1.5 m and that generally shear failure occurs in the soil. AN(8) b) All materials for foundation shall be water resistant, sufficiently strong, soil-acid resistant and immune from termite. As a result there are no many kinds of materials, which satisfy these requirements. Discuss the following materials as used in foundation construction: I. Basalt II. Trachyte III. Granite IV. Sandstone V. Shale Concrete VII. Steel AN (7) 3 c) Consolidation is the process by which there is a reduction in volume due to the expulsion of water from the pores of the soil. The dissipation of excess pore water pressure is accompanied by an increase in effective stress and volumetric strain. Discuss Time-rate of settlement AP(5) d) Discuss the process of preliminary ground investigation in foundation engineering and design AD IE a) A square foundation is 2 x 2 m in plan is to be constructed.
