报告人简介：

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 55 in Scopus attracting over 2000 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.

报告简介：

Geotechnical design and analysis involve making decisions and judgements on ground conditions where the information is incomplete. It has been estimated that less than 1 part in a million of the ground is investigated for any project. In most cases, we need to interpolate and extrapolate the information obtained from a limited number of locations to a much larger ground volume. This presentation will introduce novel tree-based methods for geotechnical site characterization based on limited site investigation data. Unlike traditional tree-based methods which use Cartesian coordinate system, the new approach uses geotechnical distance fields. The proposed geotechnical distance fields require very little additional computational cost, but can significantly improve the performance for both spatial interpolation and soil stratification problems.
