A certain soil has c ′ = 12 kPa and ∅ ′ = 32° . The major and minor total principal stresses at a point in this soil are 348 and 160 kPa, respectively, and the pore water pressure at this point is 96 kPa. Draw the failure envelope and the Mohr circle and determine if a shear failure will occur at this point in the soil. If so, determine the angle between the failure plane and the plane on which the major principal stress act

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.
