摘要

A comprehensive investigation was conducted to elucidate the consolidation characteristics of composite foundations enhanced by stone columns combined with vertical drains. The effects of drain deflection and clogging on consolidation performance were systematically evaluated under a variable well resistance framework. A governing partial differential equation was formulated with the average excess pore water pressure as the primary variable. The corresponding analytical solution was subsequently developed. Comparative numerical analyses were conducted to evaluate the differences in consolidation and settlement rates between constant and variable well resistance models. The results demonstrated that neglecting well resistance variation leads to significant overestimation of consolidation and settlement rates as well as stone column stress concentration. The proposed model was validated through its application to an airport settlement prediction, showing improved consistency with in situ measurement data when adopting the variable well resistance model.
