2- Subsurface geotechnical investigations carried out in a deposit of sand provide standard penetration numbers Ngo as given in the table below. During the g investigations, it is also observed that underground water table is encountered at a dep below the ground surface. Laboratory tests have shown that physical properties of dep are as: Dry unit weight = 17.6 kN/m and saturated unit weight = 19.6 kN/m. Detern earthquake magnitude of 8.25, if liquefaction will occur at the site. Assume that max ground acceleration at the site is: amax = 0.25g. DEPTH (M) N60 (BLOWS/30CM)
