Seismic Liquefaction Potential Assessed by Neural Networks

Abstract

The feasibility of using neural networks to model the complex relationship between the seismic and soil parameters, and the liquefaction potential has been investigated. Neural‐networks are information‐processing systems whose architectures essentially mimic the biological system of the brain. A simple back‐propagation neural‐network algorithm was used. The neural networks were trained using actual field records. The performance of the neural‐network models improved as more input variables are provided. The model consisting of eight input variables was the most successful. These variables are: the standard penetration test (SPT) value, the fines content, the mean grain size
