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.

KINDLY GET THE RIGHT ANSWER Given that B =1 m, L = 3 m, and Q = 110 kN, the soil characteristics given in the figure are Cs = 1/5 Cc, Ꝺ’c= 40 kN/m2. Field monitoring indicated that the foundation settlement was 19 mm during the first 12 months. Estimate the coefficient of consolidation for the pressure range. Estimate the settlement in 24 months.
Calculate the settlement of the 10-ft-thick clay layer that will result from the load carried by a 5-ft-square footing. The clay is normally consolidated. Use the 2:1 method to calculate the average increase of effective pressure in the clay layer. 10 ft 10 ft 10 ft 5 ft ↓ Dry sand Footing size 5 ft x 5ft Sand Clay Ydry = 100 pcf Groundwater table Ysat = 120 pcf Ysat = 110 pcf % = 1.0 LL=40
A 5-ft fill is to be placed over the following soil profile shown below. Determine if the clay is normally consolidated or over-consolidated. The pre-consolidation pressure (past maximum consolidation stress) of the clay is 1000 lb/ft3. 5 ft 2 ft 4 ft Proposed Fill, y = 120 lb/ft³ Sand Clay Rock 2 ft A Ydry = 100 lb/ft³ Ground water table Ysat 110 lb/ft³ = o'= Pc = 1000 lb/ft²
A soil profile shown is subjected to a load of 48 kN/m2 at the ground surface. The preconsolidation pressure of the clay Pc = 160 kPa. Determine the settlement of the clay layer caused by primary consolidation. Use Cs = 1/5 Cc. 48 kN/m2 ground surface 4m Sand Ys =16 kN/m³ ground water țablę 6m Y sat =18 kN/m³ Clay 3m 6m Ysat =19 kN/m³ Ans. 71 mm
Shear Stress 5. Please provide proper discussion and illustration. Clear and complete solution please thank you. A clay soil has an undrained shear strength (cohesion, Cu) of 800 psf. How could the strength of this soil be increased?
2. A 2m X 2m footing carrying 1400KN load is constructed in a site with 2.5m thick clay layer under a 2.5m thick sand layer. If the footing and the ground water table are located at 1.5m below the surface, calculate the consolidation settlement of the footing. You may assume the following soil properties: for sand sat 15.7kN/m°, and for clay eo= 0.65, Cc = 0.25, Cs = 0.06, O'p = 200kN/m² and sat =19.25KN/m³. 19.25kN/m and t = %3D
