3m #m Sand y = 16.5 kN/m 1-30 Groundwater table 5m Sand Yu-18 kNm 0-30 2. A mat foundation is shown in the figure: Size of mat: BXL = 6m x 6m (a) Determine the average net pressure on Q=15.000 KN soil caused by the mat foundation (5%). (b) Regarding the mat foundation as a uniformly loaded flexible area, estimate the stress increase caused by the mat foundation below its center at the middle of clay layer using (i) the influence factors given in the attached table (12%); (ii) the 2:1 method (8%). (c) Given: Ce = 0.48 and C=0.25 Co. Estimate the consolidation settlement of the clay layer under the center of the mat (using the larger stress increase at the middle of the clay layer calculated in (b) as the average) (15%).
