PIPING POTENTIAL OF WEAK ZONES UNDER CONCRETE DAMS

This paper presents a method that has been used to evaluate the piping potential of shear zones crossing the foundation of a concrete dam from upstream to downstream. The method may be applicable for other conditions as well. The process involves three steps: (1) Determination of the critical exit gradient for the zone in question; (2) determination of the exit gradient for the zone under reservoir conditions; and (3) comparison of the exit gradient under reservoir conditions to the critical exit gradient and determining required foundation treatment.
