Actions and effects

1 m2

Contact area per unit width x unit run An =-= 1.031-

Characteristic values at soil/rock interface:

Vertical total stress avk = Ykx H = 100 kPa avkx cos(p)

Normal total stress ank =-= 94.1 kPa

Pore water pressure uk =-= 36.9 kPa

Normal effective stress a' nk = ank - uk = 57.2 kPa Shear stress from soil t^ = avkx sin(p) x cos(p) = 23.5kPa ^ A1 ^ ^1.35 ^
