Stability analysis is a critical component of geotechnical engineering that involves evaluating the stability of soil and rock masses, slopes, embankments, retaining walls, foundations, and other structures. The effective design and efficient solutions to minimize the risk of failure can be done by identifying potential failure modes and evaluating the stability of soil and rock masses and structures. 

Stability analysis is important:

• To ensure the safety and performance of the structure or earthwork, as well as to optimize its design and construction. 
• To assess the complex geological and engineering factors 
• To predict the behavior of the soil or rock materials and the structure or earthwork under different loading conditions
