Definition: An abutment is a structure that supports the end of a bridge or other structure and retains the soil at the transition between the structure and the surrounding ground. Designing an abutment involves considering several factors, including:
Loads: Dead loads (weight of the structure itself), live loads (traffic, pedestrians), earth pressure, seismic loads (if applicable), and other environmental loads (wind, water).
Soil Properties: Bearing capacity, shear strength, settlement characteristics, and other geotechnical properties of the foundation soil.
Stability: Ensuring the abutment is stable against sliding, overturning, and bearing failure.
Settlement: Limiting settlement to acceptable levels to prevent damage to the supported structure.

Definition Continue: The formulas you provided, stability factor = abutment width * soil bearing capacity and load factor = abutment width * abutment height * live load, are simplified and don't represent a complete abutment design. Abutment design is a complex process involving multiple factors and checks for various failure modes. These formulas seem to address only a very basic comparison of bearing capacity and applied load.
