ABSTRACT
When it is a question of large dams, earth-rock ones are the most frequently constructed dams. They are constructed on rock foundation (with rare exceptions at lower dams), with a construction that is schematically presented in Figure 11.1. The shells (1) are made of coarse-graded material – gravel or rockfill, with slope inclinations which, depending on the material and foundation, most often range within limits of 1:1.5 to 1:2.2.
