Surcharge is a module in Shoring Suite. It calculates lateral
pressure on a vertical retaining system due to surcharge loads. The
program uses Boussinesq equation and modified by experiment (after
Terzaghi and Teng). It is recommended by USS design manual and NAVY
The surcharge loads can be point loads, line loads, strip loads,
area loads, or a combination of all the loads. The loads can be above
or below ground surface.
In version 8, A railroad Loading, E-80 Cooper, is added to the program.
Surcharge gives a pressure diagram and prints the pressure
changes with the depth. Instant views and hard copies are available.
It is useful for the design and analysis of retaining walls, shoring
walls, basement walls, and any flexible wall or rigid wall.
This program is also included in the Shoring Suite package. The output
can be exported to Shoring by a mouse click.
