報告簡介：
Slope failures or landslides occur annually in various countries. Despite advances in recognizing, predicting, and mitigating landslide hazards, as well as improvements in warning systems, global landslide activity continues to rise. Uncertainty is a prevalent feature in all landslides, arising at various stages—from climate data like rainfall, to infiltration rates, site characterization, material properties, analysis, design, and consequence assessment. Traditional geotechnical analysis often fails to account for these variabilities directly. Instead, "average" or "pessimistic" properties are assumed across the entire region of interest, leading to the calculation of a factor of safety that is commonly used to quantify slope stability. This single factor of safety encompasses all uncertainties.
The primary aim of this lecture is to advocate for quantitative risk assessment approaches in slope stability analyses. These approaches utilize site investigation data directly in stability analysis, rather than converting the data into parameters for use in traditional methods. By integrating finite element methods, random field theory, Monte Carlo simulations, and machine learning algorithms, these approaches provide more data-informed, quantitative assessments of slope stability risks.

Jinsong Huang is a professor at the Discipline of Civil, Surveying and Environmental Engineering, the University of Newcastle. His research interests include risk assessment in geotechnical engineering and computational geomechanics. He has published over 200 journal papers on the risk assessment of slope stability and landslides, the modelling of spatial variability, stress integration techniques for elastoplastic models, the contact dynamics of granular media, the analysis of hydraulic fracturing and the predictive maintenance of railway tracks. He has an H-index of 50 in Scopus attracting over 1800 citations per year. His contributions in risk assessment, particularly in slope stability and landslides, has earned him the prestigious title of 'Field Leader' in Environmental & Geological Engineering by The Australian's Research 2020 magazine. He received a Regional Contribution Award from the International Association of Computer Methods and Advances in Geomechanics at its international conference in Kyoto in 2014 and the GEOSNet Award from the Geotechnical Safety Network in 2017. He is a managing editor for Georisk and editorial board member for Geodata and AI, Canadian Geotechnical Journal and Computers and Geotechnics. He is a committee member on the ASCE Geo‐Institute’s Technical Committee on Risk Assessment and Management (RAM) and the ISSMGE Technical Committee (TC304) on Engineering Practice of Risk Assessment & Management. He is the chair of the Executive Board of the Geotechnical Safety Network. He served as the conference chair of the 8th International Symposium on Geotechnical Safety and Risk held at the University of Newcastle in December 2022.
