Figure below shows a soil profile. The uniformly distributed load on the ground surface is Ac. Estimate the primary consolidation settlement of the clay layer given these values: Hl=15m, H2=2m,H3=25m Sand 0.62, Gs = 2.62 Clay: 0.98, Gs =2.75, LL = 50 Ac =110 kN/m* Ao H, Sand Groundwater table

The soil profile shown below is subjected to a uniformly distributed load (UDL) on ground surface of 600 kN/m². The underground soil consist of two normally consolidated clay (N.C.C.) layers, and between them one sand layer with properties as shown on the figure. If the ground water table is at the ground surface, and the (AP) assumed to be the same at both clay layers, Calculate the total consolidation settlement Sc from the two clay layer? assume compression index, Cc=0.007(LL-10). 4.0 m 3.0 m 2.0 m Clay Sand Clay AP=600 kN/m² W, 35%.

Q 8.7 If the coefficient of consolidation for the clay layer in problem 8.3 is 0.0018 cm^2/Sec, how long will it take for 60% primary consolidation to take place? What will be the total compression due to consolidation at that time?

The thickness of a saturated specimen of clay under a consolidation pressure of 100 kN/m2 of is 24 mm and its water content is 20%. On increase of the consolidation pressure to 200 kN/m2, the specimen thickness decreases by 3 mm. Determine the compression index for the soil if the specific gravity of the soil grains is 2.70.   a.0.92 b.0.56 c.0.63 d.0.52
