摘要：

Geogrid-encased stone columns (GESCs) have shown notable potential in improving performance, thereby reducing the seismic failure probability ( P F ) of soil. This research proposes a limit equilibrium-based formulation for predicting the ultimate seismic bearing capacity ( q u ) of GESC composite foundations. Subsequently, a fragility analysis framework is developed based on the bearing capacity formula to quantify P F . The fragility analysis incorporates machine learning to evaluate the influence of tensile strength ( T ), column diameter ( ...
