In civil field, Traditional design methods employed many
theoretical formulations or analytical equations which was
derived from a simple problem with simplified boundary
conditions. It is undoubted that these analytical equations are
still useful however, they can hardly provide a total solution or
a global solution when the problem becomes more and more
sophisticate. Numerical modeling based on finite element
methods are boarded the limited of analytical methods and
significantly aimed design stage with similar to reality
conditions. However, these numerical modeling also have
several drawbacks especially for the one that depend solely on
these approach without any engineering knowledge. This paper
deals with the traditional design bearing capacity of shallow
foundations by analytical solutions, numerical solutions with
2D plane strain and 3D problems in order to highlight the
differences between these techniques and help designers better
calibrate their soil parameters for fundamental design steps
