Analysis of Soil Slope Stability in Heterogeneous and Homogeneous Soil under Leakage Based on Numerical and Limit Equilibrium Methods

Arash Aghaamini Lavasani


Any natural or artificial surfaces are called slope which can be made of soil, stone, and sometimes a combination of both. The Effects of instability and landslides in the soil slopes under leakage get clearer when slip and movement of the earth including soil and rock have devastating effects on the roads, tunnels, water and sewer lines and even buildings and so on. The slip and instabilities can cause blockage of the arteries and reduce the level of their performance and in general reduce the public safety of roads which lead to imposing enormous cost of inspection, maintenance, repair and renovating to the authorities. In critical cases, the occurrence of this instability may cause loss of life for the users of the roads in the downstream slope. The two main methods for slope stability analysis are the limit equilibrium and the numerical methods. Studying the natural and artificial slope stability and determining and assessing their reliability and stability are the common goals in the two methods. This article compares the reliability coefficients in heterogeneous soils of clay and sand with the homogeneous soils of clay obtained through the limit equilibrium and numerical methods expressions are under leakage and dryness.
