This module concerns itself with the physical properties of soils and sediments; in particular within the context of shallow engineering and environmental applications.
The module will start with the basic physical (or index) properties of a soil and explain how soils may be classified. This is followed by an explanation of effective stress, a key concept in soil mechanics. It will be apparent then, how important water is in determining soil behaviour and for that reason, ideas relating to permeability, hydraulic gradients, potential and flow nets will be presented. The flow of water within soils also plays a key role in controlling soil settlement or consolidation, and so this topic is also a part of the syllabus. Finally, concepts relating to shear strength are introduced.
Because measured soil parameters are often highly influenced by the test protocol and procedure, it is very important that an appreciation of test methods is gained. Therefore, a key element in this module is the laboratory testing programme which runs concurrently with the lecture series. Students will be introduced and allowed to perform most of the `British Standard' procedures, including index property, consolidation and strength tests.
Cynnwys cwrs
In list form, the syllabus can be summarised thus:
-
Index properties and classification schemes
-
Pore pressure, total stress and effective stress
-
Permeability, critical hydraulic gradient, potential, flow net solutions
-
1-D consolidation
-
Shear strength
The practical element will typically include the measurement of:
moisture content, specific gravity, particle size distribution, pore water salinity, density, organic matter content, carbonate content, Atterberg limits, consolidation properties, undrained shear strength
