Abstract

The role of the instrumentation on the design of earth and rockfill dams is stressed. Toe values predicted by numerical models, the behaviour of the material and the field measurements are correlated to evaluate the potencial cracking zones in embankment dams.

For the purpose of deterrnining under what conditions hydraulic fracturing would occur a parametric study of Alvito dam is performed, varying the water content of the core, the thickness of the core, and its position.
