ABSTRACT
Expression for Yo At point 0, the passive pressure acting towards the right should equal the active pressure acting towards the left, that is
A ) yK (20.1)
Expression for h For static equilibrium, the sum of all the forces in the horizontal direction must equal zero. That is
Taking moments of all the forces about the bottom of the pile, and equating to zero,
- 1 - Do 1 (- -I) h h 0P (Do+p) - - P xDox-+- P +p X x-= a 2 p 3 2 p p 3
P~ =P;+Y KDo Substituting in Eq. (20.3) for Pp' P~ and h and simplifying,
