Embankment Design, Construction, Slope Stability, Settlement Analysis and Seepage Control Workshop (
|Event Date/Time: Dec 05, 2012||End Date/Time: Dec 07, 2012|
Often conventional soil mechanics do not adequately predict the behaviour or misbehaviour of fills. However, considerable knowledge and experience on the real behaviour of real fills, has been obtained over the last decades. This knowledge expands from instrumented embankment dams to highway constructions and laboratory studies. It is important, for any civil engineer, to gain an understanding of these developments, their design and construction.
About the Program
This workshop will present some of the new techniques acquired in the following areas: material properties, mechanisms of behaviour, methods of analysis and in the problems and effects of embankment and earth works placement. the focus will be placed on those problems that have significant economic impact.
To enable participants to design and inspect embankment and earthworks effectively
To fully understand the related science and engineering principles
To interpret test results and standards
To make the best choices on embankment construction and inspection methods
To learn the most common techniques for slope and embankment stabilization
To fully comprehend slope stability analyses and the signs of potential failures
This session provides the knowledge and skills needed to design, construct and maintain soil slopes and embankments. In this three-day workshop, you will obtain a comprehensive overview of the principles and techniques of design, construction and inspection of earthworks with special focus on earthen embankment. Some of the issues that will be addressed through a presentation and a discussion with an expert practitioner are site development, soil properties, estimating, excavation, placing and compacting, and the legal and environmental considerations that bear on embankment construction. There will also be an opportunity to deal with the standards and testing methods that apply to earthen embankment. It is intended to provide transportation earthwork professionals with knowledge to recognize potential problems with soil slope/embankment stability and deformation in transportation projects. Participants will develop the necessary skills to design and evaluate soil slopes and embankments and to learn about the implications of construction and inspections. This course embraces both design and construction.
The three day workshop consists of lectures arranged in a sequence, which minimizes the need for prior knowledge of the subject.In addition, there will be discussion periods. Problems will be illustrated by numerous case-studies. Three workshops will be conducted:
Slope Stability design and analyses using software: Slope-W and SLIDE
Seepage design and analyses using software SEEP-W
Settlement Analyses using software Settle3D and UNISETTL
Upon completion of the course, participants will be able to:
Recognize potential failure modes or deformation types for soil slopes and embankments
Identify the potential failure modes for soil slopes and the type of analysis required to evaluate stability of the slope
Determine the stability of a slope using slope stability software
Recognize the major design consideration for embankments constructed using earth fill, rock fill, and lightweight fill
List the steps necessary for designing an embankment over compressible foundation soil
Distinguish the common causes/triggering mechanisms for landslides/slope instabilities
Categorize appropriate slope and embankment stabilization methods
A critical course for geotechnical professionals, foundation designers, highway / bridge design engineers, project engineers and engineering. The target audience are bridge, geotechnical, or transportation engineers with 0 to 20 years of experience, who are responsible for the design, analysis, construction maintenance and/or remediation of soil slopes and embankments on surface transportation facilities.
The course should be applicable to field and design engineers, contractors, technicians and technologists, as well as for geotechnical engineers, who wish to know more about fill behaviour.
You will receive a comprehensive set of course notes that will serve for future use.
You will also obtain training on the following software:
Slope Stability Slope-W, and SLIDE with free academic version of the GeoStudio
Seepage analysis: SEEP-W.
Settlement analyses: Settle3D and UNISETTL
