What is the formula for the factor of safety for sliding?

The factor of safety for sliding is determined by comparing the forces that resist sliding with the forces that contribute to it. This relationship is essential in geotechnical engineering, particularly when evaluating the stability of slopes or retaining structures.

The factor of safety indicates how much stronger the resisting forces are compared to the driving forces. A factor of safety greater than one suggests that the resisting forces are adequate to prevent sliding, thus ensuring stability.

By using the formula that states the factor of safety equals the forces resisting sliding divided by the forces contributing to sliding, engineers can assess whether the structural elements are designed appropriately to handle anticipated loads and conditions. This understanding helps in designing safe and resilient structures.
