The analysis of composite foundation with compound pile to resist soil liquefaction

Based on a practical engineering project , which uses composite foundation with CFG (long pile) & gravel piles (short pile) to deal with the soil liquefaction in Inner Mongolia, the composite foundation's capacity and resist liquefaction ability are analyzed in the paper. Furthermore, the design and test results of the composite foundation with CFG & gravel piles are also discussed. Above conclusion becomes territorial experience on using composite foundation with CFG & gravel piles to resist liquefaction.
