Static and Dynamic Load Transfer Behaviors of the Composite Foundation Reinforced by the Geosynthetic-Encased Stone Column

An accurate description of the load transfer behaviors geosynthetic-encased stone column (GESC) is great importance for revealing bearing capacity GESC. Static tests and shake table model were performed to characterize static dynamic composite foundation reinforced by Under loading, conducted on a fully (FGESC), partially (PGESC) traditional (TSC). The influence length stiffness encasement columns investigated. seismic analyze differences pile-soil stress responses between foundations with GESC TSC. results show that ratios FGESC are about three six times those TSC, difference increases increase in or encasement. vertical 60% acting pile top can be transferred bottom FGESC, while only 27~45% TSC first decrease then slightly input peak acceleration. ratio under excitation same type attenuation rate along body loading much faster than loading. conditions, efficacy always better
