Question
Consider the soil detail and profile are shown in the Table 1.1 and Figure 1.2. Table 1.1 Layer No. Thickness, H Soil Parameters e = 0.52, Gs = 2.62 e = 0.52, Gs = 2.65 w = 20%, e = 0.50 1 4.8 m 2 2.5 m 3 2.2 m Layer 1 H2 Layer 2 C. Layer 3 Figure 1.2 O Dry sand Sand D Clay Rock If groundwater table is x = 0.25 m above point B (use yw = 9.81 kN/m3), determine: a. The effective stress at point D. b. If the effective stress at point D is lowered by 10 kPa, what is the new elevation (new x) of groundwater table measured from point B?
