a) Determine the size of the square footing to carry net allowable load of 295 KN, F. S. = 3. Use Terzaghi equation assuming general shear failure. 295 kN + = 35° C = 0.0 Ya = 18.15 kN/m3 1 m B 0 = 25° C = 50 kN/m2 Va = 20 kN /m3 b) A group of nine friction piles of 200 mm diameter spaced at 0.6 m transfer of a load of 400 kN into a 10 m thick clay layer with sand below. It penetrates to a depth of 7 m in the clay layer. If the clay is normally consolidated with a liquid limit of 40%, estimate the probable settlement of the pile group. Assume saturated water content is 35 %; G 2.8 and the water level is at ground level, taking y = 25 kN/m³. АР (7) c) Discuss the construction of steel pile as a foundation for a proposed building project. AP(5) d) Discuss the concept of strip footing in foundation engineering and design. a) Determine the size of the square footing to carry net allowable load of 295 KN, F. S. = 3.
