Slope Stability and Monitoring
Geological and Mining Engineering
2nd Cycle Studies - Mestrado
Knowledge of Engineering Geology and Soil Mechanics.
Lectures with exposure of the subject to be taught.
- Lectures for solving exercises involving the analysis of slope stability and the results of instrumentation.
- Visits to ongoing works which were designed / implemented techniques for stabilization of slopes.
Each student should carry out detailed knowledge about:
- Understanding of the main movements of instability that may occur on the slopes.
- Ability to perform geotechnical characterization and the design of slopes.
- Knowledge of various types of instrumentation used in geotechnical works.
- Ability to prepare instrumentation plans and definition of reading programs.
- Interpretation of geotechnical characterization data and the results instrumentation.
- Easy communication with elements of a working team as well as with people who do not have expertise in the area of geotechnics.
- Application of the knowledge and ability to adapt to situations occurring in geotechnical works.
Study of natural, excavation and landfill slopes. Classifications of types of instability and its evolution. Geological and geotechnical studies) natural slopes and slopes in the design phase and b) slopes with instability. Planning and adequacy of campaigns geotechnical studies. Ruptures analysis methods in rock and soil. Deterministic analysis and safety factor. Works of stabilization. Objectives of observation and instrumentation. Notion of global risk index. Measurement displacements, stresses, groundwater levels, flow rates and forces. Characteristics of instrumentation equipment: shallow spots, piezometers, type USBR batteries, inclinometers, total stress cells, strain gauges, convergenciometers and topographical 3-dimensional system (Monmos system) .Instrumentation and observation planes in embankment dams, natural slopes, foundations in piles, underground structures and support. Security control. Determination readings "in situ" from inclinometers and piezometers.
