A clay layer, 20 feet thick is covered by a 40 foot sandy gravel stratum with a porosity of 30%, and a dry unit weight of 103 pcf. Tests on the un-drained samples of the clay gave c = 2.9 psi, YSAT = 112 psf and o' = 24°. Find: (a) the soil shear strength s = c + c'tano' at the clay's midlevel (point A), and (b) the effective and total stress acting on the vertical face of a soil element at the clay midlevel (point A). d=13" Hj=40' SAND Ya = 103 pcf n = 30% c = 2.9 psi Ysat = l12 pcf o' = 24° H3=20' CLAY ROCK
