A 10 meter soil profile consists sand overlying 3.50 m thick clay layer with porosity of 48.718% and specific gravity of 2.72. Water table is located 6.50 meters below ground surface. A 2.50 meters thick capillary rise layer is considered having a void ratio of 75.0%, degree of saturation of 60% and specific gravity of 2.71. The dry sand layer has a porosity of 33.333% and a specific gravity of 2.66. What is the total effective stress at 4 meters below. ground surface? [

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.
