Grouted gravel pile is a new technique of pile.Load transfer of this kind of pile is not expatiated because of the complex mechonism of grouted zone about the pile

which restricts development and practical application of this kind of pile.The load transfer function method is an important way to analyze load transfer mechannism of pile.According to the law of linear increase of shear strength of natural ground

a load transfer function for grouted gravel pile is obtained with linear elasto-plastic load transfer fucntion

while the effect of grouted zone is considerated.And the practicability of this method is illustrated by an actual case.
