Abstract： Reinforced composite pouring method was used in strengthening of pile foundation of two buildings in a residential community of Changsha City. This method obviously improved the lateral rigidity of pile body and pile end embedded in supporting layer and the bearing capacity of pile foundation, having favorable strengthening effects for some quality problems, such as hypostases at pile toe, solution cavity and soft interlayer, etc.

Key words： strengthening of pile foundation composite pouring method bearing capacity of pile foundation
