Web Series: Geotechnical Engineering Fundamentals
Basic Soil Mechanics Concepts
After participating in this webinar, you will be able to:
- Appreciate the importance of geology in soil mechanics.
- Determine index properties of soils.
- Characterize and classify different soils.
- Understand how water changes the states of soils.
Geotechnical engineering is a branch of civil engineering and deals with the mechanical behavior of soil and rock, and their interaction with structures. Most engineers with responsibility for design and construction of structure, energy and transportation systems need a working understanding of basic concepts of geotechnical engineering to gain confidence in dealing with a variety soil and foundation related problems that they encounter on engineering projects. This course is designed so that participants can better understand basic concepts of geotechnical mechanics (origin and formation of soil, soil types, index properties, classification).
- Origin and formation of soil: soil types
- Phase relationships in soil: index properties
- Soil description and classification
- Particle size distribution: Sieve analysis and Hydrometer tests
- Consistency of soil: clay minerals, Atterberg limits
- Stress in soil: total and effective stress
Water in Soils (Permeability and Seepage)
After participating in this lecture you will be able to:
- Determine the hydraulic conductivity (also called permeability) of soils.
- Determine the rate of flow through soil.
- Calculate flow under and within earth structures.
- Calculate pore water pressure and uplift seepage force.
- Appreciate the importance of flow of water through soils.
The flow of water in soil may cause instability and failure of many geotechnical structures (e.g., excavation, embankments, dams, roads and bridges). This lecture focuses on 1-dimensional and 2-dimensional flow of water in soil. All key concepts including the mechanism of flow, rate of flow, determination of flow rate in different applications, and flow control will be explained and emphasis will be placed on the practical application of the information provided.
- Mechanism of flow in soil
- Soil permeability
- 1D and 2D flow through soil
- Seepage analysis for dams and retaining walls
- Impact of flow of water on stability of shoring systems and dams
After participating in this seminar, you will be able to:
- Identify key issues associated with a specific slope stability problem
- Obtain parameters required for site slope stability analysis
- Select the method that is appropriate for a specific slope stability analysis
- Conduct slope stability analysis by simple calculations and assess software results
- Recommend viable options for site slope stabilization
This short course provides guidance for analyzing the static stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. Methods for slope stability analysis are described and illustrated by examples and case studies. Criteria are presented for strength tests, analysis conditions, and factors of safety.
Slope stabilization methods are also discussed with an emphasis on design of stable slopes and retaining structures.
- Basic concepts of slope stability analyses
- Common methods of slope stability analysis
- Design considerations for slopes
- Analyze stability of natural and manmade slopes
- Technologies for slope stabilization
- Stability analysis of embankment dams
- Retaining structures for slope stabilization
