WebThe horizontal Soil Subgrade Reaction in Pile Foundations is often determined using the Brom’s method (Broms, 1964). The method is widely used as it takes into consideration the length of the piles (short or long), the type of the soil (cohesive or cohesionless), and the boundary condition at the pile head (free-head or fixed-head).
