Two Square Footings G And K On Ground Surface Have The Widths Of 250 Mm And 300 Mm Respectively Their Horizontal Dista 1 (196.68 KiB) Viewed 43 times

Two square footings G and K on ground surface have the widths of 250 mm and 300 mm, respectively. Their horizontal distance is 3 m. The net contact stresses for the two footings G and K are the same and equal to 300 kPa. Estimate the maximum total additional vertical stress at the depth z = 2 m and a horizontal distance 1.0 m to the centre of the square footing G, using the Boussinesq's solution (1), 3Q z? 02(x, y, z)= (1) 2π (x2 + y2 + z2 where Q is the total additional load acting on a footing; x, y, and z are the three coordinates of a point in a Cartesian coordinate system. )
