Surcharge in non-homogeneous soil

For non-homogeneous soil we proceed as follows:

  • compute the angle υa for a given soil layer
  • determine the corresponding magnitude of force Sa  and size of the corresponding pressure diagram
  • determine the magnitude of earth pressure acting below the bottom edge of a given layer, and its ratio with respect to the overall pressure magnitude
  • the surcharge is reduced using the above ratio, then the location of this surcharge on the upper edge of the subsequent layer is determined
  • compute again the angle υa for the next layer and repeat the previous steps until the bottom of a structure is reached or the surcharge is completely exhausted
