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.

A 3m deep sand layer has a specific gravity of 2.68 and a void ratio of 0.60. Under this layer is a 2.5m deep clay profile with a specific gravity of 2.7 and a moisture content of 30%. The water table is observed at 1m below the ground surface. Determine the settlement (in mm) of a normally consolidated clay after the surcharge of 75kPa. Clay is observed to have a void ratio of 0.40 after the surcharge. (Assume unit weight of soll profile above the clay layer is the same when the soil was not subjected to surcharge load).
A 5.00m clay overlain with a 5.00m sand. The sand has a specific gravity of 2.65 and a void ratio of 0.70. The clay has a saturated unit weight of 19.22kN/cub.m, a void ratio of 0.90 and a liquid limit of 60%. The water table is located 1.00m below the ground surface and the soil above the water table is 50% saturated. A load of 75kPa is distributed on top of the ground surface. What is the overburden pressure on the mid-height of the clay layer?
Q3: Answer with false or true then correct the wrong one. 1- Up to 50 % liquid limits the soils behaves as a high plastic soil. 2- When a soil dried to shrinkage limit, it is easy to crack under pressure and considered as partially saturated. 3- The kaolinite clay formation is consisting of one silica tetrahedral sheets stacked by two aluminum octahedron sheets. 4- The piping phenomena occur at maximum effective stress value and minimum pore water pressure. 5- The water level above the ground level affects the value of the effective stresses at a certain point below the ground level. 6- Illite clay is less stable compared with montmorillonite clay due the secondary bond of potassium. 7- The summation of equipotential drops represents the difference between upstream water level and the elevation of the datum. 8- Theoretically, the plastic limit value must be less than the value of liquid limit for the same soil. 9- The specific gravity has a unit of g/cm-3. 10- The specific surface area…
