Mechanics of Earth Materials

Stress and Strain Time Scales Outline

Engineers need to not only have a basic understanding of the physical, chemical and mineralogical characteristics of rocks iand soils but also their response to applied loads , the flow of fluids and other environmental stresses. The mechanical behaviour of rocks and soils and their fluid flow characteristics as porous media are the areas of expertise of geological engineers.

The materials in geological engineering are rocks and soils. At the surface, projects include:

In the subsurface, projects in which the mechanical properties of rocks are important include the construction of: Fluids exert a very strong influence on the mechanical behaviour of rocks and soils. In addition the movement of fluids controls the location of:
