GGU-SETTLE: General

The program calculates the stresses and strains after the theory of elastic-isotropic half space. Especially in the days when pocket calculators and personal computers were not yet available, comprehensive diagrams and tables were developed. A literature list of tables can be taken from the DIN 4019. Further to this, you are referred to the article "Stress calculation" (Spannungsberechnung) in the "Geotechnical Engineering Pocket Book" (Grundbau-Taschenbuch) (1990; Fourth Edition; also available in english). Here you will also find the complete relationships for stresses and strains below a rectangle in elastic-isotropic half space (formulas 8 to 10 and formulas 14 and 15). These relationships are the basis for the program.

The stress relationships are only used for limiting depth calculations and for the presentation of stress distributions. The strains are calculated directly from the relationships given in the Geotechnical Engineering Pocket Book. A numerical integration with associated loss of precision is therefore not required.
