Soil coefficient of sliding
WebMar 5, 2024 · 2.4.2. Atterberg Limits. The Atterberg limits are a basic measure of the nature of a fine-grained soil.Depending on the water content of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties. Webeffective, allows increasing the durability of the working bodies. The coefficient of soil friction depends on many factors, the main of which are mechanical composition and humidity. Changing the ratio of solid, liquid and gaseous phases in the soil leads to a change in the forces acting in the system “soil tillage tool - soil”.
