Upstream cutoff in the concrete gravity dam foundation is introduced as a general stability measure in the beginning of the 20-th century. It become widely accepted in design practice in the late 50-ties. Nevertheless, very little is done in the stress evaluation in the cutoff zone, so far. The intention of this research is to obtain a reliable assessment of the stresses in this zone, particularly occurrence and distribution of tensile stresses, which may produce cracks. The research is based on a finite-element model, with special features in the foundation zone, and encompassed large range of dam heights, cutoff shapes, and foundation properties.
