ABSTRACT
All present soil tests are also conducted in more complex apparatus in which samples are cubic or tubular; these instruments may permit testing of soil properties in more sophisticated stress-strain situations. Analogous processes are repeated in laboratory soil sample is provided a certain density corresponding to the density in dam body, the consolidating load is relieved thereafter, the sample is again placed in the test apparatus and loaded anew. The strains must be included in the model of soil strength since the presence of volume changes brings about changes in consolidation of soil, and the latter factor obviously controls the strength of soil. A simpler estimate of ydry is given by Antipkin Once the density in dam body is known one finds k, by for clayey soil and by for cohesionless soil.
