- A 2.0 m 2.0 m square pad footing will be placed in a normally consolidated clay soil to carry a column load Q. The depth of the footing is 1.0 m. The soil parameters are: c = 0, =26, = 19 kN/m3, cu = 60 kN/m2 (=0 condition). Determine the maximum possible value for Q, considering short-term and long-term stability of the footing.
*arrow_forward*A 2.0 m 2.0 m square pad footing will be placed in a normally consolidated clay soil to carry a column load Q. The depth of the footing is 1.0 m. The soil parameters are: c = 0, = 26, = 19 kN/m3, and cu = 60 kN/m2. Determine the maximum possible value for Q, considering short-term and long-term stability of the footing.*arrow_forward*1. Solve and show solution.*arrow_forward* - a square footing with a size of 10 ft by 10 ft is located 8ft below the ground surface. the subsoil consists of a thick deposit of stiff cohesive soil with an unconfined compressive strength equal to 3600lb/ft2. The soils units weight is 128lb/ft3. calculate the ultimate bearing capacity.
*arrow_forward*Problem 1 A 3m x 3m square footing is constructed at a depth of 2m in a 26m deep clay layer with following soil properties: g =16.5kN/m3, Normally Consolidated Clay, eo= 0.65, Cc = 0.25,ms=5 and Es= 6.0 MN/m2. If there is a 1000kN structural load on the footing, calculate the consolidation settlement of the footing. 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 gsat = 19.25kN/m3 and gt = 7kN/m3, and for clay eo= 0.65, Cc = 0.25, Cs = 0.06, s’p = 200kN/m2 and gsat =19.25kN/m3. A 1882kN load is carried by a 2.6m x 2.6m square footing at a depth of 1.4m in a 30 m deep sand layer. Given the following soil properties for soil calculate the total settlement of the footing after 10 years. Where soil properties are: g = 15.9…*arrow_forward*Rectangular footing (4m x 5m) was supported by a saturated clay layer with a thickness of 5m. If the second layer (below the clay) was a saturated sand. The settlement that could be occurred in this site: a. Is only consolidation settlement b. None of the given answers are correct c. Is a short term settlement d. Is only long term settlement*arrow_forward* - Question 3. A strip footing is to be used in a clay soil in which the imposed load is 1 MN/m length. The clay layer is 7.0 m thick and overlies a stiff, fractured siltstone. The water table lies at a depth of 2.0 m. a. Determine the footing width based on the long-term allowable bearing capacity (calculated according to the method in the Canadian Foundation Engineering Manual; neglect depth factors) using a factor of safety of 3.0 for a burial depth of 2.0 m. The material properties of the clay are: c' = 15 E = 42 MPa o' = 27° y= 18.5 kN/m³ Ce = 0.40 e, = 0.90 C, = 9.3 x 104m²/day Cu = 25 b. Why would bearing capacity failure likely not govern the design of this structure?
*arrow_forward*A footing is embedded to a site of sandy clay at a depth of 1.6m below the natural grade line (NGL). The soil has the following properties: cohesion is 10kPa, angle of internal friction is 35 deg, the specific gravity of the soil solids is 2.75, void ratio is 0.55 and the water content is 5%. The water table is at a great depth. Consider Terzaghi's general shear failure and a factor of safety 3.5. Determine the bearing capacity factor for cohesion in a general shear failure condition. Select the correct response: 46.1236 33.2960 48.0287 10.6884*arrow_forward*The width and depth of a footing are 2 and 1.5 m respectively. The water table at the site is at a depth of 3 m below the ground level. The water table correction factor for the calculation of the bearing capacity of soil is*arrow_forward* - i need help quick
*arrow_forward*If the elastic modulus and the Poisson's ratio of the clay layer are respectively 50 x 10° kPa and 0.4 and if the influence factor for the strip footing is 1.75, the elastic settlement of the footing will be (a) 0.41 mm (b) 1.41 mm (d) None of these (c) 14.1 mm*arrow_forward*A rectangular footing 3m by 4m is founded 1.2m below the ground surface for which the unit weight of soil is 17.8kN/m3. The cohesion strength is 10kPa and the angle of internal friction is 20degrees. Under the condition of general failure, evaluate the contribution from the following to the ultimate soil bearing capacity in kPa. The ground water table is at a level that does not affect the unit weight of the soil. Use Terzaghi’s bearing capacity factor. For Ø=20degrees: Nc = 17.69, Nq = 7.44, Ny = 3.64. 23.
