Subsoil - Geomechanical Principles

Owing to its varying behaviour when loaded by structures, [EN1997-1:2009] classifies the subsoil into undisturbed and disturbed soil (subsequently altogether called soil) as well as rock (solid rock), while [ASTM D2487-06] just distinguishes between the various types of soil (gravels, sands, silts, clays, and organic soils).

In practice, however, a distinction between undisturbed and disturbed soil is not made. Consequently, all loose material is covered by the collective term “soil”, whereas all solid material is called “rock”.

The different types of soil are to be...

  • Classified according to [ASTM D2487-06] and [ASTM D2488];

  • Described on the basis of EN ISO 14688-1;

  • Illustrated according to DIN 4023 as well as

  • Classified under the terms of EN ISO 14688-2 and DIN 18196 [DIN1054:2010].
