- A 3 m 4 m footing, founded at 2 m depth in a clay, applies a net pressure of 200 kN/m2. The bed rock lies 10 m below the footing. The modulus of elasticity of the clay is 30 MN/m2. Using Janbus generalized relationship [Eq. (17.1)], assuming undrained conditions and flexible footing carrying uniform pressure, estimate the expected settlement.A 1.5 m square footing carries a column with a service load of 105 kN. It is founded at a depthof 2 m on a medium stiff clay with an undrained shear strength of 42 kPa, an overconsolidationratio of 4, and a plasticity index of 35. The clay layer is 5 m thick and overlies a very stiff shale.Estimate the undrained settlement of the footing using the generalized elastic method withChristian and Carrier’s (1978) influence factors.A square footing of dimension 1.5m x 1.5m carries a load of 890 kN as shown in the image: Determine the following: (d) primary settlement for normally consolidated clay using exact equation for additional pressure at midpoint of clay.

- Refer to the rectangular combined footing in Figure 10.1, with Q1 = 100 kip and Q2 = 150 kip. The distance between the two column loads L3 = 13.5 ft. The proximity of the property line at the left edge requires that L2 = 3.0 ft. The net allowable soil pressure is 2500 lb/ft2. Determine the breadth and length of a rectangular combined footing.Refer to Problem 17.7 and Figure 17.16. Suppose a footing (1.5 m 1.5 m) is constructed at a depth of 1 m. a.

Boussinesq equation 2. 1:2 MethodAn oil storage tank 35min diameter is located 2m below the surface of a deposit of clay 32mthick, which overliesa firm stratum, as shown in the scheme below. The net foundation pressures at the foundation level equal105 kN/m2. The average values of mv and pore pressure coefficient A for the clay are 0.14 m2/MN and 0.65,respectively. The undrained value of Young’s modulus is estimated to be 40 MN/m2. Determine the total settlement(excluding settlement due to secondary compression or creep) under the centre of the tank.
