Short Courses

Short Course 1: Multiphysical Analysis and Modeling of Energy Geostructures 

Instructor:  Alessandro F. Rotta Loria, Northwestern University

Description:

Energy geostructures, such as energy piles, walls, slabs and tunnels, are an innovative technology that can be used for the energy supply and structural support of any built environment by coupling the role of the geostructure with that of the geothermal heat exchanger. The energy, geotechnical and structural operation of energy geostructures involves profoundly multiphysical phenomena within and around such structures. These phenomena include, without being limited to, temperature variations, mechanically and thermally induced stress and strain variations, as well as pore water pressure variations. All of these phenomena require the integrated knowledge and the employment of adequate multiphysical mathematical formulations (e.g., analytical and numerical) and modelling tools for a successful analysis, design and application of such technology. This course addresses, without being limited to, the aforementioned knowledge and challenges, with a focus on the following aspects: How can energy geostructures be analyzed and designed from an energy, geotechnical and structural point of view? What is the thermo-hydro-mechanical behavior of energy geostructures? What is the coupled action of thermal and mechanical loads on the energy, geotechnical and structural performance of energy geostructures?

Short Course 2: Computational Modeling in Geotechnical Engineering 

Instructors:       

Ronaldo Luna, Ph.D., P.E., D.GE, F.ASCESaint Louis University

Siavash Zamiran, Ph.D., P.E., M.ASCE, Marino Engineering Associates, Inc.

Description: 

This course will present the principles of numerical modeling in geotechnical engineering practice. The main focus will be on the numerical modeling approaches based on finite element and finite difference methods using different geo-mechanical commercial programs.  We consider the geotechnical modeling aspects to span from the results of site characterization and laboratory, soil/rock properties, constitutive relations, boundary conditions, computational domain, loading; to validation and verification of results.  The modeling procedure of a retaining wall system or a small earth dam will be demonstratedas a practical example. Advanced aspects of numerical modeling including soil-structure interaction, fluid-mechanical interaction, and dynamic analysis will be discussed.  The course materials are useful for students and professionals in different engineering fields including civil, geotechnical, mining, petroleum, and geological engineering.  (note: participants are required to bring their personal computer laptop)

Short Course 3: 2D/3D Slope Stability and Seepage Analysis of Earth Dams

Instructors:       

Murray Fredlund, Ph.D., P.Eng., SoilVision / Bentley

Mitchell Bauche, B.Sc., SoilVision / Bentley

Description:

The benefits associated with performing 3D slope stability analyses were introduced in the 1970s.  Over the years a number of 3D methods of analysis have been researched. These methods have ranged from the method of columns to approaches based on variational calculus, and more recently, the use of dynamic programming. Interest in 3D slope stability analysis appears to be driven by the fact that most slope stability failures are inherently three-dimensional in character. That is, the failure surface most often represents a variation on a dish-shaped surface.  Two-dimensional representations are a significant simplification of the actual situation. It is somewhat surprising that geotechnical engineers have been as successful as they have been in using two-dimensional simplifications of three-dimensional geometries for slope stability studies.

Industry has largely embraced a two-dimensional approach with respect to slope stability analysis as an accepted method of practice and acceptable design factors of safety generally range between 1.3 and 1.5. The calibration to well-instrumented failures has typically involved performing 2D back-analyzing of failed slopes and accepting the results as a “reasonable calibration”, even though the slope failed in a 3D manner.

The first part of the first day will focus on the conceptual model building and techniques for resolving the complex 3D geometry of modern day earth dams. Methodologies for placing geotechnical designs on complex topologies will be discussed. Methodologies for quickly extracting 2D cross-sections or full 3D numerical models will also be covered.

The second part of the first day will focus on 3D slope stability and seepage modeling of large earth dams. The course will include a brief theoretical review of 2D theory but focus on 3D theory and applications. The management of complex 3D spatial data will be discussed as well as modeling methodologies related to 3D numerical modeling. The focus will be on advanced concepts of slope stability and seepage analysis and their application. Applications of 3D solutions to real-world problems will be covered.

The course is designed for practicing geotechnical and mining engineers that want to utilize the benefit of 2D or 3D numerical modeling for increasing the capabilities of their consulting firm or university research. The course also introduces the new SVOFFICE™5 Geotechnical Analysis Suite which brings new and improved cutting-edge 3D analysis capabilities to the practicing geotechnical engineer. Participants are invited to bring their own laptops to the course. They will be provided with copies of the SVOFFICE™5 software to follow along with during the short course.

Short Course 4: Communicating Your Science – Reaching Beyond Your Peers

Presenting your work to an audience of peers at a conference can feel difficult enough, but how comfortable are you explaining your work to other audiences, like family members, policy makers, or journalists? For real impact, you need to address all kinds of audiences, far beyond your peers. In this workshop, we’ll explore how to craft your message and adapt your story to difference audiences – even on the fly – so that you can ensure that your message will come across. Participants will put their skills to the test with “lightning talks” – a one-minute, slide-free summary of their work that anyone can understand and appreciate. Along the way, the workshop will give insight into the science communication process and how you can adapt it to your own projects.

The workshop will be facilitated by Dr. Nicole Sharp, a science communicator specializing in fluid mechanics and the founder/editor of the popular website, fyfluiddynamics.com.
