Question: a) A column footing 5 x 5 m is founded at 3 m at depth in a stratum of medium dense sand giving SPT

a) A column footing 5 x 5 m is founded at 3

a) A column footing 5 x 5 m is founded at 3 m at depth in a stratum of medium dense sand giving SPT = 20. Determine the immediate settlement at the surface of the centre point if the column load is 100 tons and then apply correction for depth of footing. AN (8) b) A foundation is that part of a structure which is in direct contact with the ground to which the loads are transmitted. It is the lowest part of a structure which transmits the weight of the structure, together with the effect of live loads and pressure, to the material on which the structure rests in such a manner that the underlying material is not stressed beyond its safe bearing capacity. Discuss the process of bearing capacity of soil. AP(5) c) In a normally consolidated clay of L,L = 65.5% and 5 m thickness, the overburden pressure is increased from 250 kN/m by 120 kN/m. Estimate the settlement that can take place. Assume saturated water content of 45%. AN (7) the design and d) Discuss the relevance of geotechnical methods of soil investigation construction of foundation.
