Correction: Round off your answer to the nearest multiple of ten. * A 3.2 m x 3.2 m square footing has a load of 1200 kg. From the bottom of the footing, an 8 m thick sand lies on top of a 2.8 m clay layer. The foundation is 1500 mm deep. The clay layer has LL = 48 and e = 0.95. The saturated densities of sand and clay are 1860 kg/m³ and 1760 kg/m³ respectively. Q: If the water level rises just to the ground surface and using the 2:1 method, what is the primary consolidation settlement of the clay in mm? Round off your answer to the nearest value of ten.

A rectangle pad footing with dimension bx1 = 2mx2m is subjected to axial loading N^tt = 600 kN. Foundation are constructed on ground surface shown as Figure 1. The water table is at -1.5m. The average unit weight of mass between soil and concrete above of the bottom foundation is given tb = 22 kN/m3. The results of the test of the relationship between the pressure and void ratio is shown in table. Load factor n is given n = 1.15.
