Grouted gravel pile is a new technique of pile

bearing behaviors and load transfer of this pile are studied in model test.The results of the model test show that bearing capacity of grouted gravel pile is higher than that of bottom grouting piles and plain concrete piles

and that grouting could increase frictional resistance and tip resistance.The bearing behaviors of model piles is preliminarily studied and strengthen coefficients of frictional resistance and tip resistance are obtained by the way to analyse curve of load vs settlement and curves of tip resistance vs load and settlement.Furthermore

Flac

3D

is employed to analysis grouted gravel pile model test.The bearing behaviors of grouted gravel pile is further studied and regularity of load transfer of model pile under vertical load is generalized in numerical anal

ysis.
