Risk Assessment in Geotechnical Engineering
Instructor: D.V. Griffiths, Ph.D., DSc, CEng, FICE, D.GE, P.E., Dist.M.ASCE
Update your knowledge of probabilistic methods and reliability-based design methodologies in geotechnical engineering. This short course assumes you have no more than an introductory understanding of probability and statistics, and is designed to present user-friendly training on modern probabilistic techniques for geotechnical engineering applications. The course will include:
- Discussion of potential benefits of probabilistic approaches as opposed to classical “Factor of Safety” methods. Review of sources of uncertainty in geomaterials.
- Review of some simple statistical theories needed to develop the methodologies, and how to interpret the results of probabilistic analyses. Relationship between probabilistic methods and LRFD.
- Examples of established probabilistic methods in civil engineering such as the First Order Second Moment (FOSM) method, First Order Reliability Method (FORM) and Monte-Carlo Methods (MC).
- Introduction to more advanced numerical methods of probabilistic analysis based on the finite element method, such as the Random Finite Element Method (RFEM).
- Instructions for downloading software from the instructors’ web sites at no additional cost.
Are You Prepared for the Next Disaster? A Training Short Course for Post Extreme Event Reconnaissance
Instructors: Youssef Hashash, Ph.D., P.E., F.ASCE and Joseph Wartman, Ph.D., P.E., M.ASCE
Expose a new generation of engineers to protocols for effective perishable data gathering and reporting to better understand the impact of extreme events on geotechnical systems and infrastructure. Attendees will be introduced to the use of advanced technologies such as UAV, Laser scanning, and structure from motion to efficiently collect field data. Attendees will learn through a hands-on mock team deployment exercise of the step involved in working within a team, collecting data, and producing an initial report. The course will include:
- In class training on team deployment protocols and perishable data acquisition tools.
- Hands-on training with the use of advanced equipment and mock deployments.
- We expect to have access to the Georgia Tech, Savannah Campus which we plan to use for giving lectures as well as the site whereby we demonstrate advanced reconnaissance technologies and hold mock reconnaissance team deployments.
Case Histories of Slope Instability and Stabilization for Natural and Man-Made Slopes
Instructors: Timothy D. Stark, Ph.D., P.E., D.GE, F.ASCE and Daniel Pradel, Ph.D., P.E., M.ASCE
This short course will present recent advances in slope stability analyses and shear strength assessments including static and seismic shear strength selection, two- and three-dimensional slope stability analyses, slope stabilization techniques and analyses, and demonstration of state-of-the-art limit equilibrium and finite difference software packages for evaluating slope stability.
More importantly, we will use case histories to illustrate the application of shear strength concepts and their relevance when using slope stability methods of analysis. This format will help practitioners apply modern slope stability principles to better design slope stabilizations and/or remedial measures. For this short course we propose discussing strength and related technical aspects in the morning and applying the technical information to a variety number of slope failures in the afternoon. This course will include:
- Understanding of geotechnical stability, modeling, and behavior of natural and man-made slopes.
- Understanding of the impact of external factors, such as, rainfall, timber harvesting, river erosion, and development, on landslide occurrence and runout.
- Learning design methods for slopes and valleys to minimize property damage and loss of life.
- Learning about technologies and methods to detect areas susceptible to slope failures.
- Understanding the causes and mechanisms for rainfall induced landslides.
- Learning how to identify the direction and rate of movement of slopes.
