Slippery soil is a geological phenomenon that refers

Slippery soil is a geological phenomenon that refers to the movement of a ground part compared to another part of a surface due to gravity imbalance. Although the role of gravity is the main factor causing slippage, there are other factors contributing to the imbalance of initial slope stabilization.

According to the theory of soil mechanics, there are two steady state of the roof or the wall of the pit is:

Unstable equilibrium stability (this state is suitable for measures to ensure the stabilization of the roof or the deepening of temporary structures (such as the foundations of structures)).

Stable stability (this status is suitable for measures to ensure the stabilization of the roof or the deepening of permanent structures (such as Taluy roofs for irrigation or traffic construction). ).

Natural soil, beginning to lose its stability at a slip surface. At this sliding surface, the loading load on the top and the load of the soil on the slip surface begin to overcome the balance of the consolidation of the slab. The equilibrium between the load and the consolidation of the soil on the slip surface creates the temporary stability of the roof. The consolidation load of the soil consists of two components: internal friction and stickiness of the soil.
