Keynote: AI-Driven Liquefaction Susceptibility Mapping for Offshore Wind Farms
Soil liquefaction is a major concern for offshore wind farm development in seismically active Taiwan. This study presents an artificial neural network (ANN) model trained on synthetic data based on NCEER parameters to assess liquefaction susceptibility. Among six machine learning models, the ANN achieved the highest accuracy—100% on 112 cases—while maintaining over 91% accuracy using fewer input variables. Integrated with GIS, the model was applied to 120 offshore borehole logs from western Taiwan. Results show that six of twelve wind farm sites have high liquefaction potential across all depths, with SPT-N identified as the most critical factor.
