STUDY THE SLOPE STABILITY OF EARTHEN DAM USING DIMENSIONAL ANALYSIS TECHNIQUES
Keywords:Slope Stability, Dimensional Analysis, Spencer, Earth Dam, Limit Equilibrium
Slope stability is calculated using several methods. All these methods produce estimated results based on inaccurate assumptions, and their results were particularly acceptable. Furthermore, these methods rely on supposing and segmenting the surface of failure as well as performing complex calculations. This paper introduces the “Dimensional Analysis Technique” as a new approach for dealing with earthen slopes. Four dimensionless groups ( ) were driven to calculate the slope stability of a homogeneous filtered at the downstream earth dam. Geo-Slope and Geo-Seep software are used to compute Factor of Safety by Spencer’s method. The derived formula shows that estimated upstream water levels match the calculated results and reasonably fit with coefficient of determination (R2) greater than to .97. Results suggest that the "Dimensional Analysis Technique" is a safe and new direct method to track the stability of the natural earth slope.
