Explain the practical applications of consolidated drained (CD) analysis of clay
Q6 Please provide justified answer asap
A soil investigation in an old landfill indicates 30cm of cover, SPT blow counts to -4.5m range from 1 to 8 except one boring where N=50 at -3.0. At elevation-4.5, approximately 60cm of topsoil and organic material was encountered, and begining at elevation -5 blow counts ranged from 12 to 18 to elevation -9.5. This soil was a silty stiff grey clay with traces of sand and gravel. At elevation -9.5, the soil becomes a medium dense sand with blow counts ranging from 25 to 35. At elevation -15, this soil becomes very dense and the blow counts range from 40 to 45. Boring is terminated at -19.5. The GWT is at elevation -10.5. A one storey store building of 2930m^2 is proposed for this site. Draw the typical boring log and write a self recommendations for foundations.
Figure 1 office illustrates the soil profile at a site for a proposed building. It is expected that the vertical stress at the middle of the clay layer will increase by 32 kPa. Calculate the final consolidation settlement. Ground water level is at the top of the clay layer. An oedometer test on a sample of the clay revealed that 90% consolidation on a 20-mm thick sample occurred in 40 minutes. The sample was drained on the upper and lower boundaries. Estimate the consolidation settlement in one year. Gs(clay) = 2.70 and Gs(sand) = 2.60. 5 m w = 23% Sand S = 90% w = 40% 10 m C= 0.3 OCR = 1 Clay Impervious rock Figure 1 0.9 U. avg 0.00 0.000 0.8 0.0 0.1 0.0 0.008 0.031 0.071 0.05 0.252 0.10 0.357 0.197 0.500 0.7 02 0.3 0.20 0.30 0.40 0.504 0.6 04 0.126 0.613 0.698 0.764 0.816 0.856 0.887 0.848 0.900 0.912 0.931 0.980 0.5 0.197 0.5 0.6 0.287 0.50 0.7 0.403 0.60 0.4 0.567 0.70 0.848 0.95 1.163 0,9 0.80 0.3 1.0 0.90 02 1.00 1.50 2.00 0.1 0.994 02 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 Time factor, T…
