Influence of Soil Humidity on the Stress-Strain State of Earth Dam

Abstrak

The most important stage of laying the soil in the body of the dam is its compaction. The design degree of compaction (soil density), usually expressed in terms of dry soil density, should provide sufficiently high strength, deformation and filtration characteristics of the material laid in the body of the dam. The compaction process is highly dependent on soil moisture. Compaction of the soil with the least expenditure of energy can be achieved at a certain moisture content, which is called optimal. To achieve the optimal moisture content of the laid soil in the body of the dam, the soil is moistened with water (and the waterlogged ones are dried during layer-by-layer laying) according to a special technology [2].
