A circular foundation of diameter 8 m supports a tank. The base of the foundation is at 1 m from the ground surface. The vertical load is 20 MN. The tank foundation was designed for short-term loading conditions (su = 80 kPa and Ysat = 19 kN/m³). The groundwater level when the tank was initially designed was at 4 m below the ground surface. It was assumed that the groundwater level was stable. However, Fourteen months after the tank was constructed and during a week of intense rainfall, the groundwater table reached the base of the circular footing and the tank foundation failed. It was speculated that failure occurred by bearing capacity failure. As a result of your calculations, establish and show whether this is correct or not. The friction angle is $'p = 25° from simple shear tests. 20 MN D=8m D₁ = 1 m Ground Surface

1. A soil profile for an office building foundation is on a sand layer of 10.4 meters, which is located above a normal consolidated sand soil layer with a thickness of 2 meters. Under the clay layer there is coarse sand. The groundwater level is 3 meters below ground level. The sand pore number is 0.76 and the clay moisture content is 43%. The building will exert a pressure of 140 kPa on the clay, so that the clay will undergo primary consolidation. Assume that if it rains there can be a rise in the groundwater level to the surface. So the sand can become saturated with water. Cc = 0.3 and Gs = 2.7.
A building is founded on a rectangular mat of dimensions 20 m x 10 m as shown in the plan view in figure below. A surcharge of 300 kPa is applied within the area ABCD whereas a surcharge of 100 kPa is applied within the area CDEF. Calculate the increase in vertical total stress in kPa at the depth of 5 m below Point F
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.
