Abstract：

Instead of using a deterministic approach by replacing the design parameter with a single mean number, probabilistic analysis could be used to provide better design decisions by considering all possible outcomes under parametric uncertainty. It offers a powerful alternative by incorporating uncertainty directly into the design process, providing a more comprehensive understanding of risks and performance. This approach enables engineers to quantify the likelihood of different outcomes, optimize designs, and make more informed decisions. By evaluating various scenarios and their associated probabilities, probabilistic methods help to balance safety, cost, and performance in geotechnical projects.This presentation explores the role of probabilistic analysis in geotechnical engineering, highlighting its application in design and risk management, and demonstrating how it enhances the reliability and efficiency of geotechnical solutions by linking the solution with traditional deterministic analyses with a factor of safety.

Resume:

Jim S. Shiau is currently a Professor at the University of Southern Queensland (USQ), Australia. He completed his Ph.D. at the University of Newcastle in New South Wales, Australia, under the mentorship of Professor Scott Sloan, a distinguished Rankine Lecturer and the Editor-in-Chief of Computers and Geotechnics. His research focuses primarily on deep excavations, subway tunnel engineering, foundation stability, finite element limit analysis, and shakedown analysis for geotechnical stability issues. Additionally, Professor Shiau serves on the editorial board of Soils and Foundations.With extensive experience in underground structure design and a wide-ranging interest in geotechnical stability, he has authored over 25 influential journal articles as either the first or corresponding author. He has published a total of 135 SCI/EI-indexed papers, which have been cited more than 2,100 times, earning him an H-index of 27. Professor Shiau has also organized several international conferences and forums, and in recognition of his outstanding teaching, he has been honored with the UniSQ Award for Excellence in Teaching.
