Soil mechanics

Transcribed Image Text:A foundation is to be constructed at a site where the soil profile is as shown below. The dimensions of base of foundation is 3 m x 6 m, and it carries a total load Q = 5400 KN. The initial void ratio in situe (eo = 1.38) and compression indec (Cc = 0.68) Required, 1- What is the vertical stress at midheight of the clay layer (AP) due to the foundation total load of (Q = 5400 KN), using the influence coefficient and table 10.6 shown below ? 2- What is the expected consolidation settlement of the clay layer in mm ? 3- If the bedrock is underlain the clay layer, how long it will take for 50% of consolidation settlement if the coefficienent of consolidation ( Cv = 4.96 x 10-6 m2/min. Elevation 200.0 m Water Table Water Table 7 Elevation 198.0 m 3 m by 6 m Elevation 195.5 m Sand and Gravel y= 19.83 kN/m' Elevation 192.0 m Normally Consolidated Clay y= 17.10 kN/m³ Elevation 185.6 m
